978 - وَ فِي رِوَايَةِ أَبِي اَلْحُسَيْنِ اَلْأَسَدِيِّ رَضِيَ اَللَّهُ عَنْهُ أَنَّ اَلصَّادِقَ عَلَيْهِ اَلسَّلاَمُ قَالَ: «إِنَّمَا يَسْجُدُ اَلْمُصَلِّي سَجْدَةً بَعْدَ اَلْفَرِيضَةِ لِيَشْكُرَ اَللَّهَ تَعَالَى ذِكْرُهُ فِيهَا عَلَى مَا مَنَّ بِهِ عَلَيْهِ مِنْ أَدَاءِ فَرْضِهِ وَ أَدْنَى مَا يُجْزِي فِيهَا: شُكْراً لِلَّهِ ثَلاَثَ مَرَّاتٍ.
Hadith.978 - In a narration from Abu al-Hussain al-Asadi, it is reported that Imam Jafar ibn Muhammad Al-Sadiq 
said:
“Indeed, the reason a person prays a prostration of gratitude (Sajdat al-Shukr) after completing a prescribed prayer is to thank Allah (swt), the Most High, for the blessing He bestowed upon them in enabling them to perform their obligatory duty.
The least that suffices in this prostration is to say : ‘Thanks be to Allah (swt)’ (Shukran lillah) three times.”
