"To acquire some useful knowledge is of greater merit than to perform a hundred devotional prayers voluntarily." (Ibn Majah)
"When a person dies the benefit of his/her deeds ends, except three: a continuous charity, knowledge from which benefit is derived, or a pious child praying to God for him/her." (Muslim)
Hudhayfah ibn al-Yaman said, "People used to ask the Prophet (S) about good things, but I used to ask him about bad things because I was afraid that they might overtake me. I said, 'O Messenger of Allah, we were lost in ignorance (Jahiliyyah) and evil, then Allah brought this good (Islam). Will some evil come after this good thing?' He said, 'Yes'. I asked, 'And will some good come after that evil?' He said, 'Yes, but it will be tainted with some evil.' I asked, 'How will it be tainted?' He said, 'There will be some people who will lead others on a path different from mine. YOu will see good and bad in them.' I asked, 'Will some evil come after that good?' He said, 'Some people will be standing and calling at the gates of Hell; whoever responds to their call, they will throw him into the Fire.' I said, 'O Messenger of Allah, describe them for us.' He said, 'They will be from our own people, and will speak our language.' I asked, 'What do you advise me to do if I should live to see that?' He said, 'Stick to the main body (Jamah) of the Muslims and their leader (Imam).' I asked, 'What if there is no main body and no leader?' He said, 'Isolate yourself from all of these sects even if you have to eat the roots of the trees until death overcomes you while you are in that state.'" (Bukhari, Kitab al-Fitan, 9/65)
"The righteous salaf (original Muslims) were as fearful of their good deeds being squandered, or not being accepted, as the present generation [2nd generation] is certain that their neglect will be forgiven."
'Abdallah Ibn Masud said: "The Prophet (S) said, 'Islam began as something strange, and it will revert to being strange as it was int he beginning, so good tidings for the strangers.' Someone asked, 'Who are the strangers?' He said, 'The ones who break away from their people (literally, 'tribes') for the sake of Islam.'" This hadith was narrated by Ibn Majah on the authority of Anas and Abu Hurairah. (Muslim, Kitab al-Iman, 1/90; Ibn Majah, Kitab al-Fitan 2/1320 (3988))
Hazrat Ahban bin Saifi has narrated that the Holy Prophet (pbuh) has said:
"Very shortly some differences and disputes are going to arise. When you come upon such a time break your sowrd and hold in your hand a wooden sword and sit quietly in your house, lest some mischievous hand or calamity should fall upon you." (Tirmizi)
"No doubt trials and disorders will soon occur. A man lying during the period of these disorders will be better than the man sitting and the man sitting will be better than the man standing; the man standing will be better than the man running. Then listen! when these trials and disorders begin to descend, then he who possesses camels should take refuge with his camel. He who has cattle, should take refuge with his cattle; he who has land should take refuge with his land; he who has nothing should turn his attention to his sword and strike it against stone. He should try to seek security and shelter as best as possible."
"Abu Hurairah (May Allah be pleased with him) reported Allah's Messenger (Peace be upon him) as saying: Souls are troops collected together and those who familiarized with each other (in the heaven from where these come) would have affinity, with one another (in the world) and those amongst them who opposed each other (in the Heaven) would also be divergent (in the world)." (Muslim)
