Al-Fasi(775 AH – 832 AH) in his magnum opus “Al-ʻIqd al-thamīn fī tārīkh al-Balad al-Amīn” writes:
“Abu l-‘Abbas, the son of the Imam, the eminent mystic Abu l-Hasan as-Shadili – may God have mercy on him! – often related the following: ‘I used to visit the tomb of Sidi Abu Muhammed ‘Abd ar-Razzaq (d. 595H), the companion of Abu Madyan (d. 594H). Every time I was in need of something, I would come to his tomb. Once I was in urgent need of something and thus I went to his tomb, recited a part of the Qur’an and explained the matter to him. Then I turned towards the grave, which was covered by sand(ramal), and I saw written there: Ahmad’s matter has been resolved‘”.

Note: I invite the Wahhabiyyah to be consistent in their “pure tawhid” and declare him a “Qubboori”, “Mushrik” and promoter of shirk.
