Abu l-Hasan ibn Muhammad reported from Muhammad ibn Hasan: ,,The Commander of the Faithful (a.) circled around the Ka’bah and saw a man at the curtains of the Ka’bah who was saying the blessings (Salawat) for Muhammad (s.) and his family (a.) and gave him the greeting of peace (Salam). When he passed by him the second time, he did not give him a greetings of peace, whereupon he said: ﴾O Commander of the Faithful, why did you not give me the salutation of peace this time?﴿ He said: ﴾I feared to prevent you from cursing (La’n), whereas this is better than the greeting of peace, returning the greeting of peace and wishing blessings (Salawat) upon Muhammad (s.) and the family of Muhammad (a.).﴿” [Majma’-un-Nurain of Al-Marandi, page 208]

عن أبي الحسن بن محمد عن محمد بن حسن قال: إن أمير المؤمنين كان يطوف بالكعبة فراى رجلا متعلقا باستار الكعبة وهو يصلي على محمد وآله ويسلم عليه ومر به ثانيا ولم يسلم عليه فقال يا أمير المؤمنين لم لم تسلم علي هذه المرة فقال خفت ان اشغلك عن اللعن وهو افضل من السلام ورد السلام ومن الصلوة على محمد وآل محمد
