Hadith 3736

وَقَالَ نُعَيْمٌ : عَنْ ابْنِ الْمُبَارَكِ ، أَخْبَرَنَا مَعْمَرٌ ، عَنْ الزُّهْرِيِّ ، أَخْبَرَنِي مَوْلًى لِأُسَامَةَ بْنِ زَيْدٍ ، أَنَّ الْحَجَّاجَ بْنَ أَيْمَنَ بْنِ أُمِّ أَيْمَنَ , وَكَانَ أَيْمَنُ بْنُ أُمِّ أَيْمَنَ أَخَا أُسَامَةَ لِأُمِّهِ وَهُوَ رَجُلٌ مِنْ الْأَنْصَارِ فَرَآهُ ابْنُ عُمَرَ لَمْ يُتِمَّ رُكُوعَهُ وَلَا سُجُودَهُ ، فَقَالَ : " أَعِدْ " .
The freed slave of Usama bin Zaid said, "Al-Hajjaj bin Aiman bin Um Aiman and Aiman Ibn Um Aiman was Usama's brother from the maternal side, and he was one of the Ansar. He was seen by Ibn 'Umar not performing his bowing and prostrations in a perfect manner. So Ibn 'Umar told him to repeat his prayer.

Hadith Commentary:
The first husband of Umm Ayman radi Allahu anha was Ubayd ibn Amr ibn Hilal. From him, Ayman was born, who attained martyrdom in the Battle of Hunayn. After that, Zayd ibn Harithah radi Allahu anhu married her, and from their union, Usamah ibn Zayd radi Allahu anhu was born. In this way, Ayman and Usamah were maternal brothers.

When Abdullah ibn Umar radi Allahu anhu saw Hajjaj ibn Ayman being negligent in prayer, he said: "Repeat the prayer, because you did not perform the bowing (ruku‘) and prostration (sujud) properly during the prayer." Since Abdullah ibn Umar radi Allahu anhu had witnessed the love of the Messenger of Allah sallallahu alayhi wa sallam for Zayd ibn Harithah, Umm Ayman radi Allahu anha, and their children, he deduced and said: "If the Messenger of Allah sallallahu alayhi wa sallam had seen Hajjaj ibn Ayman, he would certainly have loved him."

From this, too, the virtue of Usamah radi Allahu anhu and his family is established.
