A man writing his wife's divorce in his own hand

Ibrahim (may Allah have mercy on him) said: If someone wrote the divorce of his wife with his own hand, it takes effect.

Ali bin al-Hakam al-Bunani (may Allah have mercy on him) said: A man told me that a man wrote the divorce of his wife with his own hand on a pillow. Al-Sha'bi (may Allah have mercy on him) was asked about this, and he considered it a divorce.

Ata (may Allah have mercy on him) was asked: If a person wrote a divorce to his wife, then regretted it and held back the letter, does divorce take place or not? He said: If he held it back, no divorce takes place, and if he let it go, divorce takes place.

Al-Hasan (may Allah have mercy on him) said: If a person wrote a divorce addressed to his wife, then it occurred to him to hold back the letter, then as long as he does not speak it, it has no standing. If he sent the letter to the wife, she counts her waiting period ('iddah) from the day the letter reaches her.

Hammad (may Allah have mercy on him) said: If a man wrote a letter to his wife and wrote in it, "When this letter of mine reaches you, you are divorced," then if the letter does not reach her, no divorce takes place. And if he wrote in the letter, "Amma ba'd (to proceed): you are divorced," then divorce takes place even if the letter does not reach her.
Ibn Shubrumah said: She is divorced.
