Hud 11:74

Falamma thahaba AAan ibraheemaarrawAAu wajaat-hu albushra yujadilunafee qawmi loot

And when the fright had left Abraham and the good tidings had reached him, he began to argue [i.e., plead] with Us concerning the people of Lot.

So, when fear left Ibrāhīm and the happy news came to him, he started disputing with Us for the people of LūT.
