Reference: Siyar A’laam an-Nubalaa – v7, p430
al-Khaleel* [was of a disposition that] if he [was a cause of] benefit [to] someone with something, [then] he would not see it that he had benefitted him. And [yet] if someone [was a cause of] benefit [to] him with something, he would see it that he had indeed benefitted from him.
[And] there are some in our day and age [today] who are quite the opposite.
* al-Khaleel ibn Ahmad al-Furaahaydee, who was the the Shaykh and teacher of Seebawayh and an-Nadhar ibn Shumayl, and al-Asma’ee, and other than them. He died in 174AH.
