The Book Pertaining to the Merits of the Companions (Allah Be Pleased With Them) of the Holy Prophet - كتاب فضائل الصحابة رضى الله تعالى عنهم
حدثنا عبيد الله بن معاذ، حدثنا أبي، حدثنا شعبة، عن عدي، - وهو ابن ثابت - قال سمعت البراء بن عازب، قال سمعت رسول الله صلى الله عليه وسلم يقول لحسان بن ثابت " اهجهم أو هاجهم وجبريل معك " .
Al-Bari' b. 'Azib reported: I heard Allah's Messenger (may peace be upon him) as saying: Hassan b. Thibit, write satire (against the non-believers) ; Gabriel is with you. This hadith has been narrated on the authority of Shu'ba with the same chain of transmitters.
