Musannaf Ibn Abi Shaybah

Hazrat Shaqiq narrates that when Hazrat Khalid bin Waleed passed away, the women of Banu Mughira gathered and began to weep. People said to Hazrat Umar, "Send a message to them and forbid them from this. Has that thing not reached you from their side which is disliked!" Hazrat Umar replied, "There is no sin in the shedding of tears which they are shedding for Abu Sulaiman, as long as they do not throw dust on their heads and do not wail and cry out excessively."
