Believer's anger leads to separation
Nahj al-Balāgha|Volume 1|Book 3|Chapter 480
وصلى اللّه على سيدنا محمد خاتم الرسل، والهادي إلى خير السبل، وآله الطاهرين، وأصحابه نجوم اليقين.
May Allāh send blessings on our master Muḥammad the last of the prophets who guided us towards the best path, and his chaste descendants and his companions who are the stars of conviction.
