Bowing in Salat
إِنَّمَا وَلِيُّكُمُ اللَّهُ وَرَسُولُهُ وَالَّذِينَ آمَنُوا الَّذِينَ يُقِيمُونَ الصَّلَاةَ وَيُؤْتُونَ الزَّكَاةَ وَهُمْ رَاكِعُونَ {55}
But rather, your Guardian is Allah, and His Rasool, and those who are believing, those who are establishing the Salat and are giving the Zakat while they are performing Ruku [5:55]
[ في تفسير علي بن إبراهيم ] [ قال ] حدثني أبي، عن صفوان، عن أبان بن عثمان، عن أبي حمزة الثمالي عن أبي جعفر (عليه السلام) قال: بينما رسول الله (صلى الله عليه وآله) جالس وعنده قوم من اليهود فيهم عبد الله بن سلام، إذ نزلت عليه هذه الآية فخرج رسول الله (صلى الله عليه وآله) إلى المسجد فاستقبله سائل، فقال: هل أعطاك أحد شيئا ؟ قال: نعم، ذاك المصلي فجاء رسول الله (صلى الله عليه وآله) فإذا هو علي أمير المؤمنين (عليه السلام)
In the Tafseer of Ali Bin Ibrahim, said, ‘My father narrated to me, from Safwan, from Aban Bin Usman, from Abu Hamza Al Sumaly, from;
Abu Ja’far-asws (5th Imam) narrates: ‘Whilst Rasool-Allah-azwj was seated and in his-saww presence were a people from the Jews, among them being Abdullah Bin Salaam, when this Verse (5:55) was Revealed unto him-saww. So Rasool-Allah-saww went out to the Masjid, and a beggar faced him-saww. So he-saww said: ‘Did anyone give you anything?’ He said, ‘Yes, that Praying one’. So Rasool-Allah-saww went, and there was Ali-asws Amir Al-Momineen-asws’.[1]
