1216 - وَ رَوَى مُعَاوِيَةُ بْنُ شُرَيْحٍ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ أَنَّهُ قَالَ: «إِذَا جَاءَ اَلرَّجُلُ مُبَادِراً وَ اَلْإِمَامُ رَاكِعٌ أَجْزَأَتْهُ تَكْبِيرَةٌ وَاحِدَةٌ لِدُخُولِهِ فِي اَلصَّلاَةِ وَ اَلرُّكُوعِ.
Hadith.1216 - Mu'awiyah ibn Sharih reported from Imam Jafar ibn Muhammad Al-Sadiq 
that He said:
"If a person comes quickly while the Imam is in ruku' (bowing), one takbir (saying 'Allahu Akbar') suffices for him to enter the prayer and perform the ruku'."
