And (remember) when We took a covenant from the Children of Israel, (saying): Worship none but Allâh (Alone) and be dutiful and good to parents, and to kindred, and to orphans and Al-Masâkîn 1 (the poor), and speak good to people [i.e. enjoin righteousness and forbid evil, and say the truth about Muhammad صلى الله عليه وسلم], and perform As-Salât (Iqâmat-as-Salât), and give Zakât. Then you slid back, except a few of you, while you are backsliders. (Tafsir Al-Qurtubî).
