It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever acquires knowledge by which the Face (pleasure) of Allah should be sought, but learns it only in order to obtain some worldly goods by it, will not even find the fragrance of Paradise on the Day of Resurrection." The chain of this hadith is sahih (authentic) and its narrators are reliable on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it. A group besides Ibn Wahb also narrated it from Fulayh with a connected chain.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever learns knowledge that should be (learned) for the pleasure of Allah, but learns it only to gain some worldly benefit, will not find the fragrance of Paradise." Fulayh said (explaining) that 'arf' means its fragrance. This hadith has also been narrated with two sahih chains from Jabir bin Abdullah and Ka'b bin Malik (may Allah be pleased with them both).
