Hadith 26

Hisn al-Muslim

Chapter 15

Concerning the athan (the call to prayer)

أذكار الأذان

يَدْعُو لِنَفسِهِ بَيْنَ الْأَذَانِ وَالْإِقَامَةِ فَإِنَّ الدُّعَاءَ حِينَئِذٍ لاَ يُرَدُّ
Between the call to prayer and the 'Iqamah, you should supplicate Allah for yourself. Invocation during this time is not rejected. Reference: At-Tirmidhi, Abu Dawud, Ahmed. See Irwaa Al-Ghalil 1/262
