Al-Matalib al-'Aliyah 1640 — Encouragement to marry

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both). Sa'id bin Jubayr relates that Ibn Abbas (may Allah be pleased with them both) asked me, and this was at a time when the hair of a beard had not yet appeared on my face: "O Ibn Jubayr, have you married?" I said: No, and at present I have no such intention. He said: "Indeed, the trusts that have been placed (by Allah) in your loins will soon come forth (in the form of children)."
This report is sahih (authentic) in its chain as mawquf (a Companion's own statement), and part of it is also found in the books of Sahih.
