What must a Muslim do to avoid a decrease in reward and to prevent accumulating sins, after congregational prayers and Friday prayers have been suspended in Germany's mosques?

Whoever is deprived of prayer in the mosque due to its closure will, by God's will, be granted the full reward for the prayer. This is based on the fact that the Lawgiver indicated that a person who is prevented from an act he used to perform will receive its reward, as stated in the Hadith: "The excuse held them back." And the Ahadith indicate that a sincere intention for good accrues reward even if an excuse prevents the action. In order for his reward not to decrease and for him not to incur sins, the Muslim must be keen to obey Allah, perform congregational prayer in his home, stay away from sins, and utilize his time for what benefits him in his religion and worldly life.
