Al-Matalib al-'Aliyah 1701 — The validity of a triple divorce in one

Alqamah (may Allah have mercy on him) relates: We were present in the gathering of Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) when a man came and said: A man said to his wife that she has eight divorces? Ibn Mas'ud (may Allah be pleased with him) asked: Did you say these words all at once? He said: Yes. He asked: Do you want your wife to be separated from you? He replied: Yes. So he said: Then the matter is just as you said. Then another man came and said: A man said to his wife that tonight she has divorces equal to the number of the stars? He asked: Did you say it all at once? He replied: Yes. He asked: Do you want your wife to be separated from you? He said: Yes. At that point Sayyiduna Ibn Mas'ud (may Allah be pleased with him) said something mentioning the women of the people of the earth, which I did not remember. Then he said: Allah Almighty has made clear to you what the method of divorce is. So whoever divorces in the way that Allah Almighty has commanded, the legal ruling has been made clear for him; and whoever himself muddles and confuses the matter, we will turn his confusion back upon him. By Allah, it cannot be that you confuse your own affairs and we bear the burden of it; its ruling is just what you yourselves say with your own tongues.
This chain is mawquf (stopping at the Companion), and it is sahih (authentic) provided that Muhammad bin Sirin heard it from Alqamah; and in the narration of Imam al-Bayhaqi his explicit statement of having been told this hadith has come.
