Ibn 'Abbas said
When we were with the Commander of the believers , 'Umar b. Khattab , we reached Baida' , and there was a man under the shadow of the tree. He said to me : Go and inform me who is that person. So I went and (found) that he was Suhaib. I returned to him and said : You commanded me to find out for you who that was , and he is Suhaib. He (Hadrat 'Umar) said : Command him to see us. I said : He has family along with him. He said : (That is of no account) even if he has family along with him. So he (the narrator) told him to see (the Commander of the believers and his party). When we came (to Medina) , it was before long that the Commander of the believers was wounded , and Suhaib came weeping and crying : Alas for the brother , alas for the companion. Upon this 'Umar said : Didn't you know , or didn't you hear , that the Messenger of Allah (ﷺ) said : " The dead is punished because of the lamentation of his family" ? Then 'Abdullah made it general and 'Umar told it of certain occasions.
