Wa awfoo bi Ahdil laahi izaa 'aahattum wa laa tanqudul aimaana ba'da tawkeedihaa wa qad ja'altumul laaha 'alaikum kafeelaa; innal laaha ya'lamu maa taf'aloon
Fulfil the Covenant of Allah when ye have entered into it, and break not your oaths after ye have confirmed them; indeed ye have made Allah your surety; for Allah knoweth all that ye do.
