Muhammad Ibn Sireen said:

“I have never envied anyone over anything: if a person is going to be in the Fire, how could I envy him over some worldly matter when he is destined for the Fire?! And if he is going to Paradise, how could I be envious of a man of Paradise with whom Allâh tabâraka wa ta’âlâ is pleased?!”

[Aboo Bakr Al-Daynooree, Al-Mujâlasah wa Jawaahir Al-‘Ilm, 2931]

Muhammad Ibn Sireen said:

“There were people who abandoned knowledge and sitting with the scholars, and [instead] took to their chambers and prayed until their skin dried [from exertion in worship]. Thereafter they began to contradict the Sunnah and thus were destroyed. By Allaah, never does a person act without knowledge, except that he spoils and corrupts more than he fixes and rectifies.”

[Al-Asbahaanee, Al-Targheeb Wa Al-Tarheeb 3:98]

Muhammad ibn Seereen said:

“They used to say: so long as he is following the footsteps (of the Salaf), then he is on the right path.”
