تفسير : …in it there is no doubt (rayb)…this means that there is no uncertainty (shakk) in it. a guidance for those who are mindful of god (muttaqūn) — that is, an explanation (bayān) for those who are mindful of god. the mindful of god are those who have freed themselves from the claim of possessing any power or strength except in god, exalted is he, and who have resorted to taking refuge [in him] and depending solely on his power and strength in every situation. so god has assisted them and provided for them whence they had no reckoning, and made for them a source of relief and release from the trials to which he has subjected them.sahl [further] said:god’s power (ḥawl) and strength (quwwa) are [manifest in] his act, his act is according to his knowledge, and his knowledge is among the attributes belonging to his essence. the power and strength of the servant are but a temporary claim which lasts only until the last hour. the last hour is in the possession of god alone, exalted is he.
