Book of Knowledge

Sayyiduna Abu Hurayrah (may Allah be pleased with him) and Sayyiduna Abu Dharr al-Ghifari (may Allah be pleased with him) say: "A single chapter of knowledge that a man learns is dearer to me than (offering) a thousand voluntary rak'ahs."

These two (that is, Sayyiduna Abu Hurayrah (may Allah be pleased with him) and Sayyiduna Abu Dharr al-Ghifari (may Allah be pleased with him)) narrate that the Prophet (peace and blessings be upon him) said: "When death comes to a student of knowledge and he dies in this state (that is, while acquiring knowledge), he will be counted a martyr."
Al-Bazzar recorded it; its chain contains a narrator, Hilal bin Abd al-Rahman al-Hanafi, and he is matruk (abandoned).

Sayyidah Aishah Siddiqah (may Allah be pleased with her) narrates this saying of the Prophet (peace and blessings be upon him): "Indeed, the angels keep their wings spread for the student of knowledge, and they pray for his forgiveness."
Al-Bazzar recorded it; its chain contains a narrator, Muhammad bin Abd al-Malik, and he is kadhdhab (a liar).

Sayyidah Aishah Siddiqah (may Allah be pleased with her) narrates this saying of the Prophet (peace and blessings be upon him): "For the one who teaches goodness, everything prays for forgiveness, even the fish in the sea."
Al-Bazzar recorded it, and its chain contains a narrator, Muhammad bin Abd al-Malik, and he is kadhdhab (a liar).

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates that the Prophet (peace and blessings be upon him) said: "The scholars of this Ummah are of two kinds. (One is) a man to whom Allah Almighty has given knowledge and he spends it on the people, having no greed in that regard and taking no payment for it. For him the fish of the sea, the animals of the land and the birds in the sky pray for forgiveness. When he appears before Allah Almighty, he will appear as a leader and an honoured person, until he will be in the company of the Messengers. And (the other is) a man to whom Allah Almighty has given knowledge, and he is miserly with that knowledge towards the servants of Allah, is greedy in that regard, and takes payment for it. He will be bridled on the Day of Resurrection with a bridle of fire, and a caller will call out: 'This is the one to whom Allah Almighty gave knowledge, and he was miserly with that knowledge towards the servants of Allah, was greedy in that regard, and took payment for it.' This announcement will continue until the reckoning is finished."
Tabarani recorded it in al-Mu'jam al-Awsat; its chain contains a narrator, Abdullah bin Khirash, whom Imam Bukhari (may Allah have mercy on him), Imam Abu Zur'ah, Imam Abu Hatim and Ibn Adi declared da'if (weak), while Ibn Hibban called him thiqah (trustworthy).

Sayyiduna Jabir (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "For the one who teaches goodness, everything prays for forgiveness, even the fish in the seas."
Tabarani recorded it in al-Mu'jam al-Awsat; its chain contains a narrator, Isma'il bin Abdullah bin Zurarah, whom Ibn Hibban declared thiqah (trustworthy). Al-Azdi says: he is munkar al-hadith (his narrations are rejected), but in a case like this the statement of al-Azdi is not given consideration. The remaining narrators of this narration are the narrators of the Sahih.

Sayyiduna Abu Umamah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Indeed Allah Almighty (sends down mercy), and His angels, even the ant in its hole and the fish in the sea, pray for mercy upon the one who teaches people goodness."
Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains a narrator, al-Qasim Abu Abd al-Rahman, whom Imam Bukhari (may Allah have mercy on him) declared thiqah (trustworthy), and Imam Ahmad called him da'if (weak).
