1- رسولُ اللهِِ (صَلَّيَ اللهُ عَلَيهِ وَ آلِهِ) : المؤمنونَ إخْوَةٌ، تَتَكافى دِماؤهُم، وَهُمْ يَدٌ على مَن سِواهُم ، يَسْعى بذِمّتِهم أدناهُم.
1- The Prophet (SAWA) said, ‘The believers are brothers, their blood is coequal, and they are one hand against others, the most inferior among them is empowered by their protection [of him].’[Amali al-Mufid, p. 187, no. 13]
2- الإمامُ عليٌّ (عَلَيهِ الّسَلامُ) : رُبَّ أخٍ لَم تَلِدْهُ اُمُّكَ.
2- Imam Ali (AS) said, ‘Many a brother was not given birth by your own mother.’[Ghurar al-Hikam, no. 5351]

4- الامام الصادق (عَلَيهِ الّسَلامُ) : المُؤمنُ أخو المؤمنِ ، عَينُهُ ودَليلُهُ ، لا يَخونُهُ ، ولا يَظْلِمُهُ ، ولا يَغُشُّهُ ، ولا يَعِدُهُ عِدَةً فيَخْلِفَهُ .
4- Imam al-Sadiq (AS) said, ‘A believer is the brother of another believer, his eye and his guide; he does not betray him, nor wrong him, nor deceive him, and nor does he rescind a promise he made to him.’[Ibid. no. 3]
5- الامام الصادق (عَلَيهِ الّسَلامُ) : المؤمنُ أخو المؤمنِ كالجَسَدِ الواحدِ، إنِ اشتكَى شيئا مِنهُ وَجَدَ ألمَ ذلكَ في سائرِ جسدِهِ ، وأرواحُهُما مِن رُوحٍ واحدةٍ
5- Imam al-Sadiq (AS) said, ‘A believer is the brother of another believer, like a single body. If any part of him suffers, he will feel its pain in his entire body; and their souls are also made of one soul.’[Ibid. no. 4]
