Hadith #61

اَلْحُسَيْنُ بْنُ سَعِيدٍ عَنِ اِبْنِ أَبِي عُمَيْرٍ عَنْ جَمِيلِ بْنِ دَرَّاجٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ قَالَ قَالَ لِي:« إِنْ لَمْ تُدْرِكِ اَلْقَوْمَ قَبْلَ أَنْ يُكَبِّرَ اَلْإِمَامُ لِلرَّكْعَةِ فَلاَ تَدْخُلْ مَعَهُمْ فِي تِلْكَ اَلرَّكْعَةِ»

Al-Husayn ibn Said narrated from Ibn Abi Umayr, from Jamil ibn Darraj, from Muhammad ibn Muslim, from Abu Ja’far , peace be upon him, who said: Imam al-Baqir said to me: “If you do not catch the people before the imam (of prayer) says the takbir for the rukuh, then do not join them in that rak’ah.”
