According to this Hadīth, the Prophet (may Allah's peace and blessings be upon him) once performed the voluntary night prayer while repeating a single verse from the Qur'an again and again. According to other narrations of the same Hadīth, this verse was: {If You should punish them - indeed they are Your servants; but if You forgive them - indeed it is You who is the Exalted in Might, the Wise.} [Sūrat al-Mā'idah: 118]
