He is `Abd Allah ibn Sa`d
ibnAbi Jamra
al-Andalusi, whose lineage goes back to the great sahabi Sa`d bin
`Ibada al-Ansari, may Allah ta'ala be pleased with him. His kunya was
Abu Muhammad.
Born in al-Andalus, he was raised in the Deen. He memorized the Quran
at a young age, and became proficient in the hadith about the Prophet
Muhammad (sallAllah `aleihi wa sallam). He often used to repeat the
hadith:
"Who transmit to my umma a
single
hadith, thereby establishing the sunna or intending to call [people to
Islam], will have Janna."
He travelled around much until he settled in Egypt. His du'a was
answered, and he used to see the Prophet (sall Allah `aleihi wa sallam)
often while awake. When people heard about this, they disavowed him.
After that he isolated himself in his home, until his death year 675 H.
He is buried in al-Qurafa in Cairo, near the maqam of Ibn `Ata Allah
al-Sakandari.
In his book "Al-Mara'i al-Hisan", he describes 70 visions of the
Prophet (sallAllah `aleihi wa sallam) that occurred to him while
writing "Bahjat al-Nufus", an abridged commentary to Sahih al-Bukhari.
