Al-Matalib al-'Aliyah 2769 — Intellect and its virtue

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "For everything there is some tool and provision, and the true tool and provision of the believer is the intellect, that is, reason and wisdom; and the real pillar and support of the believer is also the intellect. Everything has a goal and final limit, and the utmost end of servitude and worship is the intellect. Every people has a guardian and protector, and the protector of the worshippers is the intellect. Every merchant has some capital and stock-in-trade, and the real capital of those who strive and toil in the path of religion is the intellect. Every household has a manager and head, and the head of the households of the siddiqin (the truthful) is the intellect. Every ruin has a restoration and building-up, and the true building-up and flourishing of the Hereafter lies in the intellect (and its right use). Every matter has a legacy and an outcome to which it is attributed and by which it is remembered, and the legacy of the siddiqin to which they are attributed and by which they are mentioned is the intellect. Every group and community has a central tent and place of refuge in which they take shelter, and the real refuge of the people of faith is the intellect."
Imam Ibn Abi al-Dunya recorded this report in 'Kitab al-Aql' (no. 24); however, its chain contains a narrator named Maysarah bin Abd Rabbih, who was a liar and a fabricator of reports, because of which the hadith scholars declared it mawdu' (fabricated).
