Jami` at-Tirmidhi 3307

Shahr bin Hawshab said:“Umm Salamah Al-Ansariyyah narrated to us, she said: ‘A woman said: “What is this Ma’ruf for which we are not to disobey in?” He (pbuh) said: “[That you not wail.]” I said: “O Messenger of Allah! Verily Banu so-and-so comforted me in the case of my uncle, and I must reciprocate for them.’ But he refused to allow me. So I asked him again numerous times, then he permitted me to reciprocate for them. So after reciprocating for the, I did not wail for anyone else until this time. And there does not remain a woman except that she has wailed besides me.’”
