Most beloved people by Prophet Muhammad[salle allahu alai hi wa sallam]
Sahih Muslim HadithHadith 6791 Narrated byAbuHurayrah
Allah’s Apostle (peace be upon him) said: The people most loved by me from amongst my Ummah would be those who would come after me but everyone amongst them would have the keenest desire to catch a glimpse of me even at the cost of his family and wealth.
In Ummah some people will kill or imprison the others.
Sahih Muslim HadithHadith 6904 Narrated byThawban
Allah’s Apostle (peace be upon him) said: Allah drew the ends of the world together for my sake. I have seen its eastern and western ends. The dominion of my Ummah will reach those ends which have been drawn together near me and I have been granted the red and the white treasures. I begged my Lord that my Ummah should not be destroyed by famine, nor be dominated by a foreign enemy who will take their lives and destroy them root and branch. My Lord said: Muhammad, whenever I make a decision, there is none to change it. Well, I grant you that your Ummah will not be destroyed by famine, nor will it be dominated by a foreign enemy who will take their lives and destroy them root and branch, even if all the people from the different parts of the world join hands together (for this purpose). However, it will be from amongst them, viz. your Ummah, that some people will kill or imprison the others.
*Note:This is exactly what is happening from many years either sectarianism/ignorance or Mutual jealousy/rivalry.For Ex:The killing of Sunnites in Iraq by Shiaites.Kuffar play games with Muslims and Muslims due to ignorance harm their brotherhood.
