Luqman 31:22

Whoever submits himself to Allah[8] and does good, has certainly grasped the firmest handhold. To Allah is the ultimate decision of all matters.

[8] i.e., obeys His commandments sincerely in words and deeds.

And whoever submits his face [i.e., self] to Allāh while he is a doer of good - then he has grasped the most trustworthy handhold. And to Allāh will be the outcome of [all] matters.

22. And whosoever submits his face (himself) to Allâh,[7] while he is a Muhsin (good-doer i.e. performs good deeds totally for Allâh’s sake without any show off or to gain praise or fame and does them in accordance with the Sunnah of Allâh’s Messenger Muhammad صلى الله عليه وسلم), then he has grasped the most trustworthy handhold [Lâ ilâha illallâh (none has the right to be worshipped but Allâh)]. And to Allâh return all matters for decision.

[7] (V.31:22) his face to Allâh i.e. follows Allâh’s religion of Islâmic Monotheism, worships Allâh (Alone) with sincere Faith in the (1) Oneness of His Lordship, (2) Oneness of His worship, and (3) Oneness of His Names and Qualities.

Whosoever surrendereth his purpose to Allah while doing good, he verily hath grasped the firm hand-hold. Unto Allah belongeth the sequel of all things.
