1203 - وَ رَوَى عَمَّارٌ اَلسَّابَاطِيُّ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: سَأَلْتُهُ عَنِ اَلرَّجُلِ يَنْسَى وَ هُوَ خَلْفَ اَلْإِمَامِ أَنْ يُسَبِّحَ فِي اَلسُّجُودِ أَوْ فِي اَلرُّكُوعِ أَوْ يَنْسَى أَنْ يَقُولَ بَيْنَ اَلسَّجْدَتَيْنِ شَيْئاً قَالَ «لَيْسَ عَلَيْهِ شَيْءٌ.
Hadith.1203 - Ammar al-Sabati narrated from Imam Jafar ibn Muhammad Al-Sadiq 
who said:
"I asked him about a man who, while praying behind an Imam, forgets to say the tasbih (glorification) during Sujood (prostration) or ruku' (bowing) or forgets to say something between the two prostrations."
Imam said: "There is no obligation upon him (no penalty)."
