[Machine] When this verse was revealed to the Messenger of Allah ﷺ , "Indeed, We have granted you, [O Muhammad], al-Kawthar. So pray to your Lord and sacrifice [to Him alone]." [Al-Kawthar: 2], the Prophet ﷺ asked Jibril: "What is this nahirah (sacrifice) that my Lord has commanded me?" Jibril replied: "It is not a sacrifice. Rather, it is when you raise your hands after saying the takbeer for prayer, when you bow, and when you raise your head from the rukoo'. Verily, it is our prayer and the prayer of the angels in the seven heavens." The Prophet ﷺ said: "Raising the hands from the interlacing of the fingers, as Allah the Blessed and Exalted said: 'So they did not render their submission to Allah, nor did they supplicate.' [Al-Mu'minun: 76]." This has been narrated and relying on what has passed, and with Allah is Tawfiq.
لَمَّا نَزَلَتْ هَذِهِ الْآيَةُ عَلَى رَسُولِ اللهِ ﷺ {إِنَّا أَعْطَيْنَاكَ الْكَوْثَرَ فَصَلِّ لِرَبِّكَ وَانْحَرْ} [الكوثر 2] قَالَ النَّبِيُّ ﷺ لِجِبْرِيلَ مَا هَذِهِ النَّحِيرَةُ الَّتِي أَمَرَنِي بِهَا رَبِّي؟ قَالَ إِنَّهَا لَيْسَتْ بِنَحِيرَةٍ وَلَكِنَّهُ يَأْمُرُكَ إِذَا تَحَرَّمْتَ لِلصَّلَاةِ أَنْ تَرْفَعَ يَدَيْكَ إِذَا كَبَّرْتَ وَإِذَا رَكَعْتَ وَإِذَا رَفَعْتَ رَأْسَكَ مِنَ الرُّكُوعِ فَإِنَّهَا صَلَاتُنَا وَصَلَاةُ الْمَلَائِكَةِ الَّذِينَ فِي السَّمَاوَاتِ السَّبْعِ قَالَ النَّبِيُّ ﷺ رَفْعُ الْأَيْدِي مِنَ الِاسْتِكَانَةِ الَّتِي قَالَ اللهُ تَبَارَكَ وَتَعَالَى {فَمَا اسْتَكَانُوا لِرَبِّهِمْ وَمَا يَتَضَرَّعُونَ} [المؤمنون 76] وَقَدْ رُوِيَ هَذَا وَالِاعْتِمَادُ عَلَى مَا مَضَى وَبِاللهِ التَّوْفِيقُ
