Chapter: The Excellence of Prayer َّدٍ عَنْ سَهْلِ بْنِ زِيَادٍ عَنِ الْوَشَّاءِ قَالَ سَ٠ِعْتُ الرِّضَا يَقُولُ أَقْرَبُ ٠َا يَكُونُ الْعَبْدُ ٠ِنَ الله عَزَّ وَجَلَّ وَهُوَ سَاجِدٌ وَذَلِكَ قَوْلُهُ عَزَّ وَجَلَّ وَاسْجُدْ وَاقْتَرِبْ. 3.

Ali ibn Muhammad has narrated from Sahl ibn Ziyad from al-Washsha’ who has said the following: “I heard al-Rida’ (a.s.), say, ’The condition wherein a servant of Allah, the Most Majestic, the Most Glorious, is nearest and closest to Him is in Sajdah. It is because of the words of Allah, the Most Majestic, the Most Glorious, “Prostrate (do Sajdah) and become close.’”” شهور - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (5/7))
