Notes:
1. All those who listen to the mu’azzin calling out the Adhan for the Friday prayers in front of the Imam, should not reply to his words. This is a more preventative ruling. [Fatawa-e-Radawiyyah]
It has been stated in al-Durr al-Mukhtar [Pg. 57]:
One should not reply with the tongue, to the words of the Adhan called in front of the imam, prior to the Khutba (sermon).
In Radd al-Muhtar Vol. 1 Pg. 575 it has been stated:
It is makruh (disliked) to reply to the (words of the) Adhan at such a time.
2. On hearing the Adhan for the Khutba, when the mu’azzin calls out the Blessed Name of the Holy Prophet, then it is best not to kiss ones thumbs at that time. The Durud Sharif (invoking blessings) on the Messenger of Allah should also be recited from the heart; not from the tongue, as remaining silent in this particular time is Fard (obligatory). This rule only applies to the adhan for the khutba, otherwise in the other adhans one should kiss their thumbs, place them on their eyes as this is Mustahab. [Fatawa-e-Radawiyyah]
In Radd al-Muhtar Vol. 1 Pg. 575, it has been stated:
The more favoured opinion is to invoke blessings (send durud) upon the Holy prophet from one’s heart (and to recite anything from the tongue).
3. To read the khutba in any language other than Arabic or to amalgamate another language with the khutba read in Arabic is disliked (makruh) and against the sunnat that has been transmitted from our pious predecessors. [Fatawa-e-Radawiyyah, Bahar-e-Shari’at]
