How can a Muslim utilize the time of answered prayer between the Adhan and Iqamah for supplication, given the closure of mosques and the absence of congregational prayers?

The hadith indicates the virtue of supplication (du'a') between the adhan and the iqama, and that Allah answers supplications made during this time. If there is no iqama in the mosque due to an epidemic or other reason, then one should estimate the time that would have been between the adhan and the iqama in that mosque. It is hoped that whoever supplicates during this estimated time will attain the virtue of supplication. The time for supplication may also be estimated as the period between the adhan and a person's individual performance of the iqama for their prayer, or their iqama for those they lead in prayer, such as their family members or in their marketplace.
