[Machine] Al-Shafi'i is reasonable, as indeed the effort in this matter is work, not effort on foot. Allah the Almighty said: "Indeed, your efforts are diverse" [Al-Layl 4]. And He said: "And your effort shall be appreciated" [Al-Insan 22]. And He said: "And whoever desires the Hereafter and exerts effort for it as it should be exerted while he is a believer" [Al-Isra 19]. And He said: "And that there is not for man except that [good] for which he strives" [An-Najm 39]. And He said: "And when he turns away [from you], he strives throughout the land to cause corruption therein" [Al-Baqarah 205]. The Sheikh said, and it has been narrated from Abu Dharr what confirms this.
