When We Learn Something New
Imām Ibn Taimiyyah, may Allāh have mercy on him, said:
A person doesn’t stop seeking [more] knowledge [of Islām] and [higher levels of] īmān.¹ If some [piece] of knowledge then becomes apparent to him that had [earlier] been hidden from him, he follows it. This [person] is not being unsteady and wavering; rather, this is someone seeking guidance that Allāh has increased in guidance, Allāh having said:
{وَقُلْ رَبِّ زِدْنِي عِلْمًا}
And say: My Lord, increase me in knowledge [of the Qurʾān and its meanings]. (Ṭā Ḥā 114, partial extract)
Majmūʿ Al-Fatāwá, vol. 22, p. 253.
¹Īmān is faith as it consists of speech, action, and beliefs; it increases with acts of obedience to Allāh and decreases with acts of disobedience to Him (trans.)
