مَنْ أَذَّنَ سَبْعَ سِنِينَ مُحْتَسِبًا، كُتِبَ لَهُ بَرَاءَةٌ مِنَ النَّارِ
Translation: Whoever gives the call to prayer for seven years seeking reward is recorded as having freedom from the Fire.

أَذَّنَ is a past-tense verb meaning “gave the call to prayer.” سَبْعَ سِنِينَ states a period of seven years. مُحْتَسِبًا describes serving while seeking reward from Allah; grammatically it is a circumstantial expression (ḥāl). كُتِبَ is passive: “was recorded,” and لَهُ بَرَاءَةٌ expresses the promised freedom from the Fire.
The adhān announces prayer and calls people to worship. The narration joins long service with sincere intention, distinguishing devoted service from performance merely for reputation.
