Al-Ma'idah 5:31

FabaAAatha Allahu ghuraban yabhathufee al-ardi liyuriyahu kayfa yuwaree saw-ataakheehi qala ya waylata aAAajaztu an akoonamithla hatha alghurabi faowariya saw-ataakhee faasbaha mina annadimeen

Then Allāh sent a crow searching [i.e., scratching] in the ground to show him how to hide the disgrace of his brother. He said, "O woe to me! Have I failed to be like this crow and hide the disgrace [i.e., body] of my brother?" And he became of the regretful.

Then, Allah sent a crow that scratched the earth to show him how he should conceal the corpse of his brother. He said, “Alas! Was I not even able to be like this crow so that I could conceal the corpse of my brother? So, he stood regretful.
