Hadith of al-Sa'di from his father from his uncle (may Allah be pleased with him)

حَدِيثُ السَّعْدِيِّ، عَنْ أَبِيهِ، عَنْ عَمِّهِ، ٢٢٣٢٩ - حَدَّثَنَا خَلَفُ بْنُ الْوَلِيدِ، حَدَّثَنَا خَالِدٌ، عَنْ سَعِيدٍ الْجُرَيْرِيِّ، عَنِ السَّعْدِيِّ، عَنْ أَبِيهِ عَنْ عَمِّهِ قَالَ: " رَمَقْتُ رَسُولَ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ فِي صَلَاتِهِ، فَكَانَ يَمْكُثُ فِي رُكُوعِهِ وَسُجُودِهِ قَدْرَ مَا يَقُولُ: سُبْحَانَ اللهِ وَبِحَمْدِهِ ثَلَاثًا " (١)، ،

Sa'di, may Allah have mercy on him, narrates from his father or uncle that I have observed the manner of the Prophet Muhammad's (peace be upon him) prayer. The Prophet Muhammad (peace be upon him) used to remain in bowing (ruku') and prostration (sajdah) for the duration in which "Subhan Allah wa bihamdihi" could be said three times.
