Oneness, Uniqueness of Allah (Tawheed)

"‏ لاَ وَمُقَلِّبِ الْقُلُوبِ ‏"

The Prophet (ﷺ) frequently used to swear, "No, by the One Who turns the hearts."

"‏ إِنَّ لِلَّهِ تِسْعَةً وَتِسْعِينَ اسْمًا مِائَةً إِلاَّ وَاحِدًا، مَنْ أَحْصَاهَا دَخَلَ الْجَنَّةَ ‏"

Allah's Messenger (ﷺ) said, "Allah has ninety-nine Names, one-hundred less one; and he who memorized them all by heart will enter Paradise." To count something means to know it by heart.

"‏ إِذَا جَاءَ أَحَدُكُمْ فِرَاشَهُ فَلْيَنْفُضْهُ بِصَنِفَةِ ثَوْبِهِ ثَلاَثَ مَرَّاتٍ، وَلْيَقُلْ بِاسْمِكَ رَبِّ وَضَعْتُ جَنْبِي وَبِكَ أَرْفَعُهُ، إِنْ أَمْسَكْتَ نَفْسِي فَاغْفِرْ لَهَا، وَإِنْ أَرْسَلْتَهَا فَاحْفَظْهَا بِمَا تَحْفَظُ بِهِ عِبَادَكَ الصَّالِحِينَ ‏"

The Prophet (ﷺ) said, "When anyone of you goes to bed, he should dust it off thrice with the edge of his garment, and say: Bismika Rabbi Wada`tu janbi, wa bika arfa'hu. In amsakta nafsi faghfir laha, wa in arsaltaha fahfazha bima tahfaz bihi 'ibadaka-s-salihin."

حَدَّثَنَا مُسْلِمٌ، حَدَّثَنَا شُعْبَةُ، عَنْ عَبْدِ الْمَلِكِ، عَنْ رِبْعِيٍّ، عَنْ حُذَيْفَةَ، قَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم إِذَا أَوَى إِلَى فِرَاشِهِ قَالَ ‏"‏ اللَّهُمَّ بِاسْمِكَ أَحْيَا وَأَمُوتُ ‏"‏‏.‏ وَإِذَا أَصْبَحَ قَالَ ‏"‏ الْحَمْدُ لِلَّهِ الَّذِي أَحْيَانَا بَعْدَ مَا أَمَاتَنَا وَإِلَيْهِ النُّشُورُ ‏"‏‏.‏

When the Prophet (ﷺ) went to bed, he used to say, "Allahumma bismika ahya wa amut." And when he woke up in the mornings he used to say, "Al-hamdu li l-lahi al-ladhi ahyana ba'da ma amatana wa ilaihi-nnushur."

"‏ بِاسْمِكَ نَمُوتُ وَنَحْيَا، فَإِذَا اسْتَيْقَظَ قَالَ الْحَمْدُ لِلَّهِ الَّذِي أَحْيَانَا بَعْدَ مَا أَمَاتَنَا وَإِلَيْهِ النُّشُورُ ‏"

When the Prophet (ﷺ) went to bed at night, he used to say: "Bismika namutu wa nahya." And when he got up in the morning, he used to say, "Al hamdu li l-lahi al-ladhi ahyana ba'da ma amatana, wa ilaihi-nnushur."

"‏ لَوْ أَنَّ أَحَدَكُمْ إِذَا أَرَادَ أَنْ يَأْتِيَ أَهْلَهُ فَقَالَ بِاسْمِ اللَّهِ، اللَّهُمَّ جَنِّبْنَا الشَّيْطَانَ، وَجَنِّبِ الشَّيْطَانَ مَا رَزَقْتَنَا‏.‏ فَإِنَّهُ إِنْ يُقَدَّرْ بَيْنَهُمَا وَلَدٌ فِي ذَلِكَ لَمْ يَضُرُّهُ شَيْطَانٌ أَبَدًا ‏"

Allah's Messenger (ﷺ) said, "If anyone of you, when intending to have a sexual relation (sleep) with his wife, says: Bismillah, Allahumma jannibna ashShaitan, wa Jannib ash-Shaitana ma razaqtana, Satan would never harm that child, should it be ordained that they will have one. (Because of that sleep).

"‏ إِذَا أَرْسَلْتَ كِلاَبَكَ الْمُعَلَّمَةَ وَذَكَرْتَ اسْمَ اللَّهِ فَأَمْسَكْنَ فَكُلْ، وَإِذَا رَمَيْتَ بِالْمِعْرَاضِ فَخَزَقَ فَكُلْ ‏"

I asked the Prophet, "I send off (for a game) my trained hunting dogs; (what is your verdict concerning the game they hunt?" He said, "If you send off your trained hunting dogs and mention the Name of Allah, then, if they catch some game, eat (thereof). And if you hit the game with a mi'rad (a hunting tool) and it wounds it, you can eat (it).

"‏ اذْكُرُوا أَنْتُمُ اسْمَ اللَّهِ وَكُلُوا ‏"

The people said to the Prophet (ﷺ) , "O Allah's Messenger (ﷺ)! Here are people who have recently embraced Islam and they bring meat, and we do not know whether they had mentioned Allah's Name while slaughtering the animals or not." The Prophet (ﷺ) said, "You should mention Allah's Name and eat."

حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا هِشَامٌ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، قَالَ ضَحَّى النَّبِيُّ صلى الله عليه وسلم بِكَبْشَيْنِ، يُسَمِّي وَيُكَبِّرُ‏.‏

The Prophet (ﷺ) slaughtered two rams as sacrifice and mentioned Allah's Name and said, "Allahu-Akbar" while slaughtering).

"‏ مَنْ ذَبَحَ قَبْلَ أَنْ يُصَلِّيَ فَلْيَذْبَحْ مَكَانَهَا أُخْرَى، وَمَنْ لَمْ يَذْبَحْ فَلْيَذْبَحْ بِاسْمِ اللَّهِ ‏"

That he witnessed the Prophet (ﷺ) on the Day of Nahr. The Prophet (ﷺ) offered prayer and then delivered a sermon saying, "Whoever slaughtered his sacrifice before offering prayer, should slaughter another animal in place of the first; and whoever has not yet slaughtered any, should slaughter a sacrifice and mention Allah's Name while doing so."
