It is narrated about Sayyiduna Rafi‘ bin Sinan (may Allah be pleased with him): He accepted Islam, but his wife refused to accept Islam. They had a daughter named ‘Umairah. The woman demanded custody of the child, but Sayyiduna Rafi‘ (may Allah be pleased with him) refused. Both of them presented themselves before the Prophet (peace and blessings of Allah be upon him). The Prophet (peace and blessings of Allah be upon him) said to the woman: "You sit here." He said to Sayyiduna Rafi‘: "You sit here." Then he said: "Now both of you call the child." Both of them called her, and the child inclined towards her mother. So the Prophet (peace and blessings of Allah be upon him) prayed: "O Allah! Grant her guidance." Then the child inclined towards her father, so he took her and went away with her.

Tawoos narrates: Abu Sahba came to Sayyiduna Ibn Abbas (may Allah be pleased with them), so Sayyiduna Ibn Abbas (may Allah be pleased with them) said to him: "Present your stance (or question), and whatever is in your mind, and whatever you have gathered." So Abu Sahba said to him: "Do you know? In the time of the Noble Prophet (peace and blessings be upon him), three divorces were counted as one." So Sayyiduna Abdullah bin Abbas (may Allah be pleased with them) replied: "Yes, in the time of the Noble Prophet (peace and blessings be upon him), in the caliphate of Sayyiduna Abu Bakr (may Allah be pleased with him), and in the early period of the caliphate of Sayyiduna Umar (may Allah be pleased with him), three divorces were counted as one. But when, in the time of Sayyiduna Umar (may Allah be pleased with him), divorce cases became frequent, then Sayyiduna Umar bin Khattab (may Allah be pleased with him) started to count them as three."

Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) narrates: I heard the Noble Prophet (peace and blessings be upon him) saying: "O Mu'adh! Whoever divorces his wife with an innovated (i.e., contrary to Sunnah) method—whether one, two, or three divorces—we will impose his innovation upon him."

Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) said: "O Mu'adh! Whoever divorces his wife with one, two, or three divorces in an innovated (bid'ah) manner, We will make his innovation binding upon him."

Narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both): "Whoever gives his wife three divorces during her menstruation, then the woman will become irrevocably separated from him, however, that person has disobeyed his Lord and violated the Sunnah."

This narration is also transmitted with another chain of transmission.

Aban bin Taghlib narrates: I asked Imam Ja'far al-Sadiq about a man who gives his wife three divorces. Imam Ja'far al-Sadiq said: "That woman becomes separated (bainah) from that man and she will not be lawful for him until she marries another man and becomes a widow or is divorced." I asked him: "Should I give people a fatwa according to this?" He replied: "Yes."

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them) narrates: "The Noble Prophet (peace and blessings be upon him) considered khul‘ to be an irrevocable divorce."

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: The wife of Sayyiduna Thabit bin Qais (may Allah be pleased with him) took khul‘ from him, so the Prophet (peace and blessings be upon him) instructed that woman to observe one menstrual period as her ‘iddah.

Ikrimah narrates: Thabit's wife (then as in the previous hadith), they mentioned (in its chain) Sayyiduna Ibn Abbas, may Allah be pleased with them both.
