Islam is the only 'religion' chosen by Allah - a complete system of life. A Muslim has to lead a life on the basis of Islam in all aspects of life from birth to death. Islam has different principles in all aspects of personal, family, social, national and international life.
Allah says in the Holy Quran –

Pronunciation: Innad deena 'indal laahil Islaam;

Meaning: Surely Islam is the only religion acceptable to Allah.

(Surah Al-Imran: Verse 19)

Pronunciation: Alyawma akmaltu lakum deenakum wa atmamtu ‘alaikum ni’matee wa radeetu lakumul Islaama deenaa;

Meaning: “This day I have perfected for you your religion and completed My favor upon you and have approved for you Islam as religion.”

(Surah Maidah: Verse 3)

In daily life, everyone should always remember Allah, fear Allah and live according to the rules of Allah. Just as people follow Islam in their daily life, so they encourage other people to follow Islam.

There are different Doas (blessings) for every good deed in our life which the Prophet Muhammad (SM) recited in his daily life. Reading these Doas and doing those deeds brings blessings and success as well as Sawab.

The great Prophet said: “Dua is the essence of worship.”

(Tirmizi: 3371)

And he also said, Dua is the worship”

(Tirmizi: 2969)

Dua for waking up:

ﺍَلْحَمْدُ لِلَّهِ الَّذِي أَحْيَانَا بَعْدَ مَا أَمَاتَنَا وَإِلَيْهِ النُّشُورُ

Pronunciation: Alhamdu lillaahil-lathee ahyaanaa ba da maa amaatanaa wa ilayhin-nushoor.

Meaning: Praise is to Allah Who gives us life after He has caused us to die and to Him is the return.

Dua for sleeping:

اَللَّهُمَّ بِاسْمِكَ أَمُوتُ وَأَحْيَا

Pronunciation: Allahumma bismika amutu wa ahya.

Meaning: “O Allah, with Your Name will I die and live (wake up)”.
The Great Prophet (SM) used to recite the above Doa putting his hands under his right cheek while lying in his bed at night.

Doa Before Eating a Meal:

بِسْمِ اللَّهِ وَ عَلَى بَرَكَةِ اللهِ

Pronunciation: Bismillahi wa ’ala barakatillah.

Meaning: In the name of Allah and with the blessings of Allah, we eat meals.

If we forget to recite Doa when we start eating a meal; then as soon as we remember we will recite the following Dua.

بِسْمِ اللَّهِ أَوَّلَهُ وَآخِرَهُ

Pronunciation: Bismillahi awwalahu wa akhirahu.

Meaning: “In the Name of Allah, in the beginning and the end.”

Dua when we complete our Meal:

بِاَلْحَمْدُ لِلّهِ الَّذِيْ اَطْعَمَنَا وَ سَقَانَا وَ جَعَلَنَا مِنَ الْمُسْلِمِيْن

Pronunciation: Alhamdulillahilladhii ath’amanaa wa saqaanaa wa ja’alanaa minalmuslimiin.

Meaning: Praise be to Allah Who has fed us and given us drink, and made us Muslims.

If someone does not say Bismillah before eating, Saitan participates in that food with him. Saitan cannot eat anything from that food when someone starts eating with Bismillah.

And if one starts eating without saying Bismillah and then recites the Dua for eating, then Satian is forced to vomit whatever he eats.

(Muslim)

The Prophet (SM) said, "Saitan considers the food which does not bear the name of Allah to be halal for him."

Eating a meal with right hand

The Great Prophet (SM) used to eat his meal with right hand all his life. He forbade eating with left hand. The Prophet (SM) said, “None of you should eat and drink with his left hand, for the Saitan eats and drinks with left hand.”

(Bukhari - 5376, Muslim - 2020)

If any food fell during eating the meal, the Prophet (SM) pick it up and eat it. He said, “When any one of you drops a mouthful, he should remove anything filthy from it and then eat it, and should not leave it for the Saitan.”

(Muslim - 2034)

Dua before going to the toilet:

بِاَللَّهُمَّ اِ نِّىْ اَعُوْذُ بِكَ مِنَ الْخُبْثِ وَالْخَبَائِثِ

Pronunciation: Allahumma innee aAAoothu bika minal-khubthi wal-khaba-ith

Meaning: (In the name of Allah). O Allah, I take refuge with you from all evil and evil-doers.

After reciting the above dua, the left foot should be inserted in the toilet first.

You should not sit on the toilet with face or back towards the qibla.

(Bukhari -144)

Dua when leaving the toilet:

بِغُفْرَانَكَ الْحَمْدُ لِلهِ الَّذِيْ اَذْهَبَ عَنِّيْ الْاَذَى وَعَافَانِيْ

Pronunciation: Ghufra-naka Alhamdulillah-hilla-thee ath-haba ann-nil athaa wa 'afaani.

Meaning: "(O Allah) I seek forgiveness and pardon from You. All Praise be to Allah, who removed the difficulty from me and gave me ease (relief)”.

The bathroom or toilet is an unclean and dirty place. Saitan lives in unclean and filthy places. Saitan sees us if we don't recite the Dua when we enter the toilet. But if we recite the Dua before entering the toilet, then Saitan can no longer see us and can't do any harm. By reciting this Dua we take refuge to Allah Ta'la.

Doa for entering home:

بِاللَّهُمَّ إِنِّي أَسْأَلُكَ خَيْرَ الْمَوْلِجِ وَخَيْرَ الْمَخْرَجِ بِسْمِ اللَّهِ وَلَجْنَا وَبِسْمِ اللَّهِ خَرَجْنَا وَعَلَى اللَّهِ رَبِّنَا تَوَكَّلْنَا

Pronunciation: Allahumma inni As’aluka khayral Mawlaji wa khayral makhraji. Bismillahi Walajna Wa Bismillahi kharajna, Wa ’alal-lahi Rabbina Tawakkalna.

Meaning: “O Allah, I ask of You the good of entering and the good of leaving (this home). With Allah’s name we enter and eith his name we leave and upon Allah, our sustainer, do we rely.”

The Prophet (SM) said: “When one of you enters a house and remembers Allah at the time of entering and eating, Saitan calls his companions and says: You have no place to stay and you have no food for dinner.”

(Muslim)

Doa for leaving home:

بِسْمِ اللهِ تَوَكَّلْتُ عَلَى اللهِ وَ لَا حَوْلَ وَ لَا قُوَّةَ اِلَّا بِاللَّهِ

Pronunciation: Bismil-lahi Tawakkaltu Aaalal-lahi, Wala Hawla Wala Quwwata illa Billah

Meaning: “In the name of Allah, I place my trust on Allah, and there is no might nor power except with Allah.”

The Prophet (SM) said, “When a man goes out of his house and says this doa the following will be said to him at that time: "You are guided, defended and protected." The devils will go far from him and another devil will say: How can you deal with a man who has been guided, defended and protected?”

What should we do if we yawn?

Yawning comes because of laziness and inertia. And this is come from Saitan. So, when we yawn, we should check our yawning as much as possible. Because when someone yawns, Saitan laughs at him.

(Bukhari: 3289)
