Hazrat Salim says that the verse of the Holy Qur’an { وَلاَ یَعْصِیْنَکَ فِیْ مَعْرُوفٍ } means not to wail.

(12481) [*] Ubayd Allah ibn Musa narrated to us, Usama ibn Zayd narrated to us, from Nafi‘, from Ibn ‘Umar who said: The Messenger of Allah صلی اللہ علیہ وسلم returned on the day of Uhud and heard the women of Banu ‘Abd al-Ashhal weeping over their dead, so he said: "But Hamza has no weepers." So the women of the Ansar came (weeping) over Hamza. He lay down and then woke up and said: "Woe to them, they are still here until now. Tell them to return and not to weep over any dead after today." (3).
