Musannaf Ibn Abi Shayba 37:88

Abu Usama narrated to us, from Mujalid, from Abu al-Safar, from a man from Banu Abs, who said: Hudhayfah said to us, "How will you be when Allah causes the affair of the nation of Muhammad, may Allah bless him and grant him peace, to be lost?" A man said, "You keep bringing us something abominable—that Allah would cause the affair of the nation of Muhammad to be lost!" He said, "Do you see, if one who does not weigh a mosquito's wing in the sight of Allah is put in charge of it, do you think the affair of the nation of Muhammad has been lost on that day?"
