عَنْ أَنَسِ بْنِ مَالِكٍ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((الدُّعَاءُ لَا يُرَدُّ بَيْنَ الْأَذَانِ وَالْإِقَامَةِ))
It is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: The supplication made between the adhan and the iqamah is not rejected.
