Is seeking knowledge, acting upon it, and inviting to it among the causes for entering Firdaus, and is it the best deed qualifying one to enter it?

Firdaus is the highest and central part of Paradise. Above it is the Throne of the Most Merciful, and from it spring forth the rivers of Paradise. Righteous believers can enter it if they fulfill its conditions of strong faith and good deeds that have reached the pinnacle of sincerity and righteousness. A seeker of knowledge, if he fulfills his obligations, strives in supererogatory acts, avoids forbidden things, fills his time with seeking sound knowledge and teaching it with sincerity and truthfulness, and asks Allah for Firdaus, then he is among those for whom its attainment is hoped for by the grace of Allah. Sound and pure knowledge raises the ranks of its possessor, opens a door to the status of the truthful (Siddiqiya), and brings a great, continuous reward after death.
