Hadith #46

رَوَى اَلْحُسَيْنُ بْنُ سَعِيدٍ عَنْ صَفْوَانَ عَنِ اِبْنِ بُكَيْرٍ عَنْ عُمَرَ بْنِ أَبِي شُعْبَةَ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: قُلْتُ لَهُ أَكُونُ مَعَ اَلْإِمَامِ فَأَفْرُغُ قَبْلَ أَنْ يَفْرُغَ مِنْ قِرَاءَتِهِ قَالَ« فَأَتِمَّ اَلسُّورَةَ وَ مَجِّدِ اَللَّهَ وَ أَثْنِ عَلَيْهِ حَتَّى يَفْرُغَ»

Al-Husayn ibn Said from Safwan, from Ibn Bukayr, from Umar ibn Abi Shubah, from Abu Abdillah , said: I said to Imam al-Sadiq : “I am with the imam (of prayer), and I finish before he finishes his recitation.” Imam said: “Then complete the Surah and glorify Allah and praise Him until he finishes.”
