Ahmad ibn Idris has narrated from Muhammad ibn ‘Abd al-Jabbar from Safwan from ibn Bukayr who has said the following: “Abu ‘Abd Allah (a.s.), has said, ‘A man who gets up in the end of the night to perform his nightly optional Salah (prayer), all of them at one time and goes away to sleep, is not very praiseworthy.” وثق كالصحيح - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (5/409))
