Musannaf Ibn Abi Shaybah 18666 — Sunnah divorce: what it is and when

Humayd bin Abd al-Rahman al-Himyari (may Allah have mercy on him) said that news reached Sayyiduna Abu Musa (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) was displeased with the people. Sayyiduna Abu Musa (may Allah be pleased with him) came to the Prophet (peace and blessings be upon him) and mentioned it, and he (peace and blessings be upon him) said: One of you says, 'I have married!' 'I have divorced!' This is not the way of the Muslims. Divorce the woman at the beginning of her 'iddah. (So that counting the 'iddah is easy for her.)
