Also the doubling of the rewards for good deeds during that time as mentioned in Usool Kafi and other books quoting Ammar Saabaati that he said: “I asked Abu Abdillah, peace be upon him: ‘Which is better, worship [‘ibadah] in secret with a hidden Imam from among you [in the time] of government by an illegal ruler, or worship in the time of the manifestation of the Truth [al-Haqq] and its government with the manifest Imam from among you?’ He said: ‘O Ammar, the giving of alms, which is a form of worship in secret is better, by Allah, than giving openly; similarly, by Allah, your worship in secret with your hidden Imam in the time of government of an illegal ruler, and your fear of your enemy in the time of government of an illegal ruler and in a state of truce with your enemy, is better than that you should worship Allah, may remembrance of Him be made Mighty and Majestic, in the time of the manifestation of the Truth with the Imam of Truth which is manifest in the time of the government of Truth.

Worship while you fear in the time of government of an illegal ruler is not the same as worship and security in the time of the government of Truth.
