This may be interpreted as referring to absolute imitation which implies Kufr and necessitates parts of it to be Haraam. Sometimes it may be interpreted as meaning that he is one of them to the extent that he imitates them. If it (i.e., imitating concerning) is in ideas of Kufr, Masiyah (sin) or the Shiar (signs and partaking in a ritual) then its Hukm (ruling) will be accordingly. (Iqtida’us Siraat’il Mustaqim, 1/271)

2. From the benefits (of this report): is knowing how devout Ibn ʿUmar (may Allah be pleased with him and his father) was in his following of the Prophet ﷺ. 2 - (ومنها): ما كان عليه ابن عمر رضي الله تعالى عنهما من شدة الاتباع للنبيّ -صلى الله عليه وسلم-، He (may Allah be pleased with him) was maʿrūf (ie: well known) for that. فكان معروفًا بذلك، ʿAbd Allah b. Wahb narrated from Mālik, from someone who told him that Ibn ʿUmar used to follow the order of the Messenger of Allah ﷺ, trace his footsteps and show great concern for emulating his composure, so much so that some were concerned for his sanity because of his level of involvement in that. فروى ابن وهب، عن مالك، عمن حدثه أن ابن عمر كان يتبع أمر رسول الله -صلى الله عليه وسلم-، وآثاره، وحاله، ويهتمّ به، حتى كان قد خيف على عقله من اهتمامه بذلك. Khārijah b. Muṣʿab narrated that Mūsá b. ʿUqbah heard Nāfiʿ saying: “Had you seen how devoutly Ibn ʿUmar used to follow the Messenger of Allah ﷺ you would have considered him majnūn (ie: insane)!” وعن خارجة بن مصعب، عن موسى بن عقبة، عن نافع، قال: لو نظرت إلى ابن عمر إذا اتبع رسول الله -صلى الله عليه وسلم-، لقلت: هذا مجنون. On the authority of ʿAbd Allah b. ʿUmar, Nāfiʿ said that Ibn ʿUmar used to trace the footsteps of the Messenger of Allah ﷺ, going to every place he prayed. وعن عبد الله بن عمر، عن نافع، أن ابن عمر كان يتّبع آثار رسول الله -صلى الله عليه وسلم- كلّ مكان صلّى فيه، The place where the Prophet ﷺ took rest under a tree once, was a place Ibn ʿUmar used to maintain later on, watering the tree so it would not dry up. حتى إن النبيّ -صلى الله عليه وسلم- نزل تحت شجرة، فكان ابن عمر يتعاهد تلك الشجرة، فيصبّ في أصلها الماء؛ لكيلا تيبس. Nāfiʿ said that after Ibn ʿUmar narrated the ḥadīth from the Messenger of Allah ﷺ requesting a certain door to be left for the women to use, Ibn ʿUmar refrained from using the door until he died. وقال نافع، عن ابن عمر، قال: قال رسول الله -صلى الله عليه وسلم-: "لو تركنا هذا الباب للنساء"، قال نافع: فلم يدخل منه ابن عمر حتى مات. These reports have all been mentioned by al-Ḏahabī in his book, “as-Siyar”. ذكر هذا كله الذهبيّ في "السير". Muḥammad b.

Ibn Umar narrated: "When the Muslims arrived in AI-Madinah, they used to assemble for the Salat, and guess the time for it there was no one who called for it (the prayer). One day they discussed that and some of them said that they should use a bell like the bell the Christians use. Others said they should use a trumpet like the horn the Jews use. But Umar [bin Al-Khattab] said: 'Wouldn't it better if we had a man call for the prayer?'" He said: "So Allah's Messenger said: 'O Bilal! Stand up and call for the Salat.'" JAMI' at-TIRMIDHI: The Book on Salat (Prayer): Hadith 42/304

Ibn Umar narrated that : the Prophet said: "Whoever misses the Asr prayer, then it is as if he was robbed of his family and his property." JAMI' at-TIRMIDHI: The Book on Salat (Prayer): Hadith 27/304

Abdullah ibn Umar (ra) [Sahih Bukhari, Kitab-ul-Imaan]

Mujahid narrated that Ibn 'Umar said: "The Messenger of Allah (saw) grabbed me and said: 'Be in the world like a stranger or a passerby, and count yourself among the inhabitants of the grave.'" Ibn 'Umar said to me: "When you wake up in the morning, then do not concern yourself with the evening. And when you reach the evening, then do not concern yourself with the morning. Take from your health before your illness, and from your life before your death, for indeed O slave of Allah! You do not know what your description shall be tomorrow." [Tirmidhi, 2333]
