And when My servants ask you regarding Me [they should know that], I am near, and I answer the prayer of the one who prays when they pray to me. Therefore, they should respond to Me and have faith in Me in order that they may be led aright.
اللّهُـمَّ رَبَّ هَذِهِ الدّعْـوَةِ التّـامَّة وَالصّلاةِ القَـائِمَة آتِ محَـمَّداً الوَسيـلةَ وَالْفَضـيلَة وَابْعَـثْه مَقـامـاً مَحـموداً الَّذي وَعَـدْتَه
O Allah, Master of this perfect call and the prayer that we are going to perform, gives Muhammad the power to intercede (the Day of Judgment) and the place of honor [in Paradise], and resurrect him in the laudable position that You promised him
عَنْ أَنَسِ بْنِ مَالِكٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: الدُّعَاءُ لَا يُرَدُّ بَيْنَ الْأَذَانِ وَالْإِقَامَةِ
According to Anas Ibn Mâlik, the Prophet (sallallahu 'alayhi wa sallam) said: The invocations between Athan and Iqâmah are not rejected
The Prophet (peace and blessings of Allah be upon him) said "Whoever does the ablutions perfectly then goes to jumua and then listens and is silent, he is forgiven what is between that time and the following Friday and three more days and the one who touches stones has certainly made a futility"
