Ibn Kathir said:
فتحت في رمضان من هذه السنة، وذلك أن نور الدين استغاث بعساكر المسلمين فجاؤوه من كل فج ليأخذ ثأره من الفرنج، فالتقى معهم على حارم فكسرهم كسرة فظيعة، وأسر البرنس بيمند صاحب إنطاكية، والقومص صاحب طرابلس، والدوك صاحب الروم، وابن جوسلين، وقتل منهم عشرة آلاف، وقيل: عشرين ألفا.
وفي ذي الحجة منها فتح نور الدين مدينة بانياس، وقيل: إنه إنما فتحها في سنة ستين، فالله أعلم.
وكان معه أخوه نصر الدين أمير أميران، فأصابه سهم في إحدى عينيه فأذهبها، فقال له الملك نور الدين: لو نظرت لما أعد الله لك من الأجر في الآخرة لأحببت أن تذهب الأخرى.
In this year in Ramadhan Harim was conquered. Nur ud din asked help of Muslim armies and they came to him from everywhere to take revenge from crusaders, They fought them in Harim and had a crushing victory against them. And captured the Prince Bohemund of Anitoch, Hakim of Tripolial Qumas, Sahib of Rome and son of Joscelin. Killed 10,000 of them and some say 20,000.
And in Dhul hajjah Nur al din won the city of Baniyas..in which eye of his brother Naseer ud din was injured due to an arrow. Nur al din said to him, If you would see what Allah has prepared for you in the aakhirah you would ask for your second eye to be injured as well.
