Stated Imaam al-Albaanee, “Therefore, the key to the return of the glory of Islaam means implementation of beneficial knowledge and establishing righteous and correct actions, and this is a very great affair which the Muslims cannot reach, except through the methodology (manhaj) of tasfiyah (purification and correction) and tarbiyah (education and cultivation). There two are very great obligations. By the first of these (tasfiyah), the following is intended:

1. Purifying the Islaamic ‘aqeedah from that which is alien to it, such as shirk, ta’teel (denial of Allaah’s Attributes), ta’weel (figurative interpretation), refusing authentic ahaadeeth, because they are connected to matters of ‘aqeedah, and their like;
2. Purifying the Islaamic fiqh (jurisprudence) from erroneous judgements which are contrary to the Qur’aan and the Sunnah, freeing the minds from the fetters of blind-following and the darkness of sectarianism and party spirit.
3. Purifying the books of tafseer, fiqh, raqaa’iq (matters concerning the heart) and other than that from the ahaadeeth that are weak and fabricated, or the unsupported narrations from the people of the Book, and the reprehensible narrations.

With regards to the second obligation (tarbiyyah), then by it I mean: cultivating the young generation upon this Islaam, purified from all that we have mentioned, giving them a correct Islaamic education from the start – without any influence from the disbelieving western education. There is no doubt that bringing these two obligations about requires huge efforts and sincere cooperation between all Muslims, individuals and groups, from all those who are truly concerned with establishing the desired Islaamic society, each one working in his own field and speciality.” Refer to Fiqhul-Waaqi’ (p.49-51).
