(Ali-Imran) 3 : 170
فَرِحِينَ بِمَا آتَاهُمُ اللَّهُ مِنْ فَضْلِهِ وَيَسْتَبْشِرُونَ بِالَّذِينَ لَمْ يَلْحَقُوا بِهِمْ مِنْ خَلْفِهِمْ أَلَّا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ

Rejoicing with whatever Lord Allah has bestowed from His Bounty, and Heralding with those left behind who have not yet joined with them that no need to fear upon them, and for them will not be grieved.

Anyone who enters Paradise will be satisfied to live in It forever and he will never seek for transferring from there as told in verse 18: 108. It is taught by the Lord through His Messenger that those who become a martyr in the way of the Lord will wish to come again to the world and to be martyred again because of the splendid rewards and enjoyments they have in Paradise. Based on this teaching Caliph Umar, Usman, Ali, etc. who participated in the Battle of Badr, Battle of Uhud, the Battle of Khandhaq, Tabuk expedition, and the battles after the Messenger’s departure used to pray for martyrdom. That is why they were killed by the hypocrites and become Martyrs.

Since there is no group of believers anywhere in the world, there is no war in the cause of the Lord and so there is no martyrdom today. But the odd believer should do Jihad with Adhikr against the Arabic Quran reading Fujjar as told in verses 9: 73 and 25: 52. He will follow a lifestyle explained in verses 7: 205-206. See explanation 2: 154; 3: 79, and 102.
