Al-Bayhaqi recorded in his book Al-Adab, Chapter on Love for one’s Brother:
Anas ibn Malik reported: The Prophet, peace be upon him, said:باب: لا يؤمن أحدكم حتى يحب لأخيه ما يحب لنفسهChapter: None of you have faith until he loves for his brother what he loves for himself
Abdullah ibn Umar reported: The Messenger of Allah, peace be upon him, said:لا يُؤْمِنُ أَحَدُكُمْ حَتَّى يُحِبَّ لأَخِيهِ مَا يُحِبُّ لِنَفْسِهِNone of you have faith until he loves for his brother what he loves for himself.
[Sahih Bukhari, Volume 1, Book 2, Number 15]
Abu Al-Mughirah reported: I said, “O Messenger of Allah, inform me of a deed that will bring me closer to Paradise and distance me from Hellfire.” He, peace be upon him, said:مَنْ أَحَبَّ أَنْ يُزَحْزَحَ عَنِ النَّارِ وَيَدْخُلَ الْجَنَّةَ فَلْتُدْرِكُهُ مَنِيَّتُهُ وَهُوَ مُؤْمِنٌ بِاللَّهِ وَالْيَوْمِ الآخِرِ، وَيَأْتِي عَلَى النَّاسِ مَا يُحِبُّ أَنْ يُؤْتَى إِلَيْهِWhoever loves to avoid Hell and enter Paradise, then let death overtake him while he has faith in Allah and the Last Day, and he treats the people they way he loves to be treated.
[ٍSahih Muslim, Book 020, Number 4546]
تُقِيمُ الصَّلاةَ، وَتُؤْتِي الزَّكَاةَ، وَتَحُجُّ الْبَيْتَ، وَتَصُومُ رَمَضَانَ، وَتُحِبُّ لِلنَّاسِ مَا تُحِبُّ أَنْ يُؤْتَى إِلَيْكَ، وَتَكْرَهُ لَهُمْ مَا تَكْرَهُ أَنْ يُؤْتَى إِلَيْكَEstablish prayer, give charity, perform pilgrimage to the House, fast the month of Ramadan, and love for people what you would love to come to yourself, and hate for people what you would hate to come to yourself.
[Musnad Ahmad, Number 15453]
