An Excellent Khutbah based upon the following Ayah in which Allah says:
“And say to My slaves (i.e. the true believers of Islamic Monotheism) that they should (only) say those words that are the best. (Because) Shaitan (Satan) verily, sows disagreements among them. Surely, Shaitan (Satan) is to man a plain enemy.” [Surah Al-Israa. Ayah 53]
Excerpt
How many – O slaves of Allaah- enmities and wars broke out due to one evil statement, and how much love, brotherhood and [amicability, hospitality, cordiality etc] spread between the slaves due to one good statement!
It is better to respond to the muadhin and then supplicate after that, with what has been reported1, then he enters into (performing) tahiyyatul masjid (2 rakah before sitting down), however some of the scholars have made an exception when entering the mosque on the Friday and the muadhin is calling the second adhaan, (if that occurs) he (first) prays tahiyyatul masjid , so that he is able to listen to the khutbah. The reason for that is because listening to the khutbah is an obligation and responding to the muadhin is not an obligation. And safeguarding the performance of an obligation takes precedence over safeguarding (the performance of) that which isn’t an obligation.

O Allah , Lord of this perfect call and established prayer. Grant Muhammad the intercession and favor, and raise him to the honored station You have promised him, [verily You do not neglect promises].
