It is narrated from Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "One of you says to his wife: 'I have divorced you; I have taken you back.' This is not the (Sunnah) divorce of the Muslims. Divorce the woman at the start of her purity (that is, at the beginning of the state of purity, in accordance with the waiting period)."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Abu Khalid al-Dalani except Abd al-Salam bin Harb."
