[Its chain of transmission is daif] Ibn Adi narrated it in al-Kamil, 7/2676, from the hadith of Ahmad bin Abdah, through the same chain, with an unknown man in it. On this subject there is also a report from Bara, referring to the hadith of Ahmad, 4/289, and elsewhere, and from Ibn Umar, which I could not locate. The hadith "There is no staying up at night except for one who prays or one who is traveling," etc., has already been mentioned above, under number 169. The report of Abdul-Rahman bin Yazid and others is daif, since Abu Ishaq narrated with anaan.
