Abu Dawud Book 2, Hadith Number 1104.

Chapter : Not known.

Narated By Buraydah ibn al-Hasib : The Apostle of Allah (PBUH) delivered a speech to us; meanwhile al-Hasan and al-Husayn came upon there stumbling, wearing red shirts. He came down from the pulpit, took them and ascended it with them. He then said: Allah truly said: “Your property and your children are only trial” (Ixiv.15). I saw both of them, and I could not wait. Afterwards he resumed the speech.
