And (remember) when We took a covenant from the Children of Israel, (saying): Worship none but Allah (Alone) and be dutiful and good to parents, and to kindred, and to orphans and Al-Masakin (the poor), [Tafsir At-Tabari, Vol. 10, Page 158 (Verse 9:60)] and speak good to people [i.e. enjoin righteousness and forbid evil, and say the truth about Muhammad Peace be upon him], and perform As-Salat (Iqamat-as-Salat), and give Zakat. Then you slid back, except a few of you, while you are backsliders. (Tafsir Al-Qurtubi, Vol. 2, Page 392).
