Ibn Qayyim was the father of two sons, Abdullah and Ibrahim, both of whom went on to follow in his footsteps and become excellent scholars in their own right.
Abdullah, the second of Ibn Qayyim's two sons, was very intelligent, talented and mature for his age and was blessed with an equally excellent memory. He memorised Surah Al-A'raf in two days and lead Salah while he was only nine years old. After the death of his father, he assumed responsibility of Sadriyyah instead of his older brother.
During his tenure inn this position, he was known for his sharpness in wisdom, eagerness to defend Allah's Deen and struggle against bid'ah [innovations in religion] of the day.
Ibrahim meanwhile was both a grammarian as well as a jurist. In addition to also teaching at Sadriyyah along with his younger brother and possessing a good reputation due to his legal verdicts and Islamic knowledge, he also authored many books, the most famous of which is Irshad As-Salik Ila Hall Alfiyyah Ibn Malik; a commentary on Sheikh Alfiyyah Ibn Malijk.
