سورة المائدة · 5:7

7. Remember Allah’s favour upon you by guiding you to Islam and the promise He took from you when you said at the time of pledging allegiance to the Prophet (peace be upon him) to listen and follow in ease or difficulty: ‘We hear your words and we follow your instruction’. Be mindful of Allah by fulfilling His instructions, including His promises, and avoiding His prohibitions. Allah knows what is in the hearts and nothing is hidden from Him.
