´It was narrated that Abu Ad-Darda' said:` "The Messenger of Allah (ﷺ) said: 'Whoever established Salah, pays Zakah, and dies not associating anything with Allah, he has a right from Allah the Mighty and Sublime, that He will forgive him, whether he emigrated, or died in his birthplace.' We said: 'O Messenger of Allah! Shall we not tell the people about it so that they may rejoice?' He said: 'In Paradise there are one hundred levels, (the distance) between each two of which is like (the distance) between the Heaven and the Earth; Allah has prepared them fro the Mujahidin who strive in His cause. Were it not that it would be too difficult for the believers and I cannot find mounts for them - and they do not like to stay behind if I go out (on a campaign) - I would not have stayed behind from any expedition. I wish that I could be killed then brought back to life, then killed again.'"

1؎: In this way, I will be able to attain the highest and loftiest rank and status in Paradise, so you too should not consider merely entering Paradise to be sufficient, but rather strive to attain the highest of ranks. Thus, just as faith (iman) is sufficient for forgiveness, advancement in the ranks of Paradise is dependent upon striving (jihad).
