(Imām Bukhārī narrates): Mu'ādh ibn Asad narrated to us, he said: Al-Fadl ibn Mūsā informed us, he said: Sa'īd ibn 'Ubaid al-Tā'ī informed us, from Bashīr ibn Yasār al-Ansārī, from Anas ibn Mālik al-Ansārī, may Allāh be pleased with him, he narrates that:

he came to Madīnah. He was asked: Since the time of the Messenger of Allāh ﷺ has passed, what thing do you find changed (contrary to what it used to be)? He said: I find nothing changed except that you do not keep the rows straight.

And 'Uqbah ibn 'Ubaid said, from Bashīr ibn Yasār: Anas ibn Mālik came to us with this same saying.
