It is narrated from ‘Urwah bin Zubair that there was a mukhannath (a naturally impotent man, whose name was Hit) with Sayyidah Umm Salamah (may Allah be pleased with her). He said to ‘Abdullah bin Abi Umayyah, while the Messenger of Allah (peace and blessings be upon him) was listening:“O ‘Abdullah! If tomorrow Allah, the Glorious and Exalted, grants you victory over Ta’if by your hand, then you must take the daughter of Ghilan. When she comes forward, four folds are visible on her belly, and when she turns her back, eight folds are visible (four on each side).”The Messenger of Allah (peace and blessings be upon him) said:“These people should not come to you.”

Yahya ibn Sa'id narrated that he heard from Qasim ibn Muhammad, who said: There was an Ansari woman with Sayyiduna Umar ibn al-Khattab (may Allah be pleased with him), and from her a boy was born whose name was Asim ibn Umar. Then Sayyiduna Umar ibn al-Khattab (may Allah be pleased with him) separated from that woman and came to the Mosque of Quba. There he found Asim playing with the boys in the courtyard of the mosque. Sayyiduna Umar ibn al-Khattab (may Allah be pleased with him) took hold of his arm and mounted him on his animal. The boy’s maternal grandmother, seeing this, argued with him and demanded her boy. Then both of them came to Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him). Sayyiduna Umar ibn al-Khattab (may Allah be pleased with him) said: He is my son. The woman said: He is my child. Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him) said to Sayyiduna Umar ibn al-Khattab (may Allah be pleased with him): Leave the boy and give him to his grandmother. Sayyiduna Umar ibn al-Khattab (may Allah be pleased with him) remained silent and did not argue further.

Imam Malik (may Allah have mercy on him) said: The practice is according to this hadith.
