And nothing has prevented Us from sending Signs except that the former peoples denied them, and We gave Thamud the she-camel as an Insight, but they wronged to her, and We don’t send Signs except as a terror.
Meccan pagans have asked for Signs from Lord to prove that Muhammad is a Messenger of Lord. Lord has revealed Signs for previous Messengers’ people, but they denied Adhikr and the Messengers. Messenger Swalih who was sent to Thamud people was given a she-camel as Sign is explained in verses 11: 66-68. The Three-Time-Knower Lord teaches that nobody will become believers by revealing Signs.
Today, the Arabic Quran reading Fujjar who hide and reject Adhikr are hurrying for the Antichrist and Doomsday. Shortly, by the proclamation of Mahdi at Hejaz, the believers all over the world will be separated to thereby expelling every Fujjar from there. By the departure of the last forerunner believer from this world, the 10 crucial Signs for Doomsday will occur one by one as explained in verse 6: 158. By the second coming of Jesus and killing Antichrist, these Fujjar will be killed by the other people belonging to Messenger’s community. Then only they will approve that not the Arabic Quran but Adhikr/Dhikree was the Lord’s Book as told in verse 38: 8. See explanation 13: 31; 14: 11 and 16: 93.
