A muezzin will rise reciting the azan

Sayyidunā Jābir رَضِىَ اللّٰهُ عَـنْهُ reports that the final Prophet صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم said, “Indeed, those who announce the azan and those who recite the talbiyyah [i.e., لَبَّیْک اللّٰہم لبیک] will rise from their graves on the Day of Judgement while reciting the azan and talbiyyah.”^[1]

Virtue of going early for the prayer

It is written in Mukāshafat al-Qulūb:

When the Day of Judgement arrives, a group of people will rise from their graves and their faces will be shining like the stars. The angels will ask them, “What actions did you perform [which granted you these blessings]?” They will answer, “As soon as we heard the azan, we left all our activities and performed ablution.” Another group will rise, and their faces will be glowing like the moon. The angels will ask them about their actions, and they will reply, “We performed ablution and prepared for the prayer before its time.” Then another group will rise, and their faces will be luminous like the sun. The angels will ask about their deeds, and they will answer, “We would listen to the azan after arriving at the masjid [i.e., we would arrive at the masjid before the azan was announced].’^[2]

Fragrant smell emitting from their mouths

Sayyidunā Anas bin Mālik رَضِىَ اللّٰهُ عَـنْهُ said:

When the Day of Judgement commences, those who fasted will rise from their graves with a powerful fragrance like musk emanating from their mouths, and they will be recognised by this
