Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 46
وَ رَوَى إِسْمَاعِيلُ بْنُ مُسْلِمٍ عَنِ اَلصَّادِقِ عَنْ أَبِيهِ عَلَيْهِمَا اَلسَّلاَمُ أَنَّهُ قَالَ: «إِذَا سَجَدَ أَحَدُكُمْ فَلْيُبَاشِرْ بِكَفَّيْهِ اَلْأَرْضَ لَعَلَّ اَللَّهَ يَدْفَعُ عَنْهُ اَلْغُلَّ يَوْمَ اَلْقِيَامَةِ.
Ismail ibn Muslim narrated from Imam Al-Sadiq, from his father عليه السلام, who said: "When any of you performs Sujood (prostration), let them place their palms directly on the ground, so that Allah سبحانه وتعالى may protect them from shackles on the Day of Judgment."
