Sayyiduna Imran bin Husayn (may Allah be pleased with him) said: We travelled by night with the Messenger of Allah (peace and blessings be upon him), then the Prophet (peace and blessings be upon him) halted with us in the last part of the night and slept. Then he woke up and the sun had already risen, so each man among us began rising in alarm towards his purification. The Prophet (peace and blessings be upon him) said: "Move on," so we set off until, when the sun had risen high, we halted, relieved ourselves and performed ablution. Then he (peace and blessings be upon him) ordered Bilal (may Allah be pleased with him), so he called the adhan and we prayed two rak'ahs. Then Bilal called the iqamah and the Prophet (peace and blessings be upon him) led us in prayer. We said: O Messenger of Allah, shall we pray it again tomorrow at its proper time? He (peace and blessings be upon him) said: "Would your Lord forbid you usury (riba) and then accept it from you?"
