Before the prohibition of riba by Allah, the Mighty and Majestic, when the Prophet, peace and blessings be upon him, had forbidden the repetition of that prayer the next day after he had commanded it, and he informed his companions that Allah, the Mighty and Majestic, does not prohibit riba and then accept riba from His servants, and two prayers for one prayer is like a dirham for two dirhams, and likewise with whatever is not permissible to have disparity in.

Sayyiduna Imran bin Husayn (may Allah be pleased with him) narrates that we traveled at night with the Messenger of Allah (peace and blessings of Allah be upon him), and when the last part of the night came, we camped and sleep overcame us. Then only the heat and warmth of the sun woke us up. So everyone rushed anxiously towards the water for ablution, and the Messenger of Allah (peace and blessings of Allah be upon him) ordered them and they performed ablution. Then he ordered Sayyiduna Bilal (may Allah be pleased with him), and he gave the call to prayer (adhan). Then he prayed the two sunnah of Fajr. Then the Prophet (peace and blessings of Allah be upon him) ordered Bilal, and he gave the iqamah. Then they said, "O Messenger of Allah (peace and blessings of Allah be upon him), we have been greatly negligent. Should we not repeat it at this time tomorrow?" So he (peace and blessings of Allah be upon him) said: "Your Lord forbids you from usury."
