Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Abdullah that he said: Adhere to obedience and the congregation, for indeed it is the rope of Allah which Allah has commanded to hold fast to. And indeed, the things you dislike in the congregation are better than those you like in separation. Allah Almighty has not created anything except that He has appointed its end. This religion has certainly been perfected and now it is heading towards decline. And the sign of this decline is that family ties will be severed, unlawful wealth will be taken, blood will be shed, a relative will complain about his close relatives that they give him nothing, a beggar will go around for two Fridays but nothing will be placed in his hand. People will be in this state when suddenly the earth will make a sound like a cow. All the people will think that it is making the sound from their side. While people are in this state, suddenly the earth will bring forth its treasures, that is, gold and silver. After that, there will be no benefit from this gold and silver.
