Salaam & Greeting

Saying the salaam slowly

Q:

- حَدَّثَنَا عَلِيُّ بْنُ حُجْرٍ قَالَ: حَدَّثَنَا عَبْدُ اللَّهِ بْنُ المُبَارَكِ، وَهِقْلُ بْنُ زِيَادٍ، عَنْ الأَوْزَاعِيِّ، عَنْ قُرَّةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ الزُّهْرِيِّ، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ: «حَذْفُ السَّلَامِ سُنَّةٌ» قَالَ عَلِيُّ بْنُ حُجْرٍ: وَقَالَ ابْنُ المُبَارَكِ: " يَعْنِي: أَنْ لَا تَمُدَّهُ مَدًّا «هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ، وَهُوَ الَّذِي يَسْتَحِبُّهُ أَهْلُ العِلْمِ» الترمذي حذف السلام: الإسراع به التلخيص الحبير وَفِيهِ «حَذْفُ السَّلَامِ فِي الصَّلَاةِ سُنَّة» هُوَ تَخْفِيفُهُ وتَرْك الْإِطَالَةِ فِيهِ. النهاية

Would saying the salam slowly and not quickly be contrary to the sunnah

Replying to salaam at the time of azaan, while eating or reciting Qur'an

Q: The Fuqaha have mentioned that at the time of tilawaat, azaan and eating, if salaam is made to a person then the salaam does not have to be returned. What is the hukam if a person returns the salaam at these times? Is there karaaha in a person doing so or will it be permissible to reply although the salaam does not have to be returned?

Replying to salaam correctly

Q: A known person to me sometimes greet me as Assamualekum without la in it, clearly. Sometimes I reply to him in forgetfulness Walekum assalam, instead of Walekum. Then I realize that, and don't know what to read as a counteract to that. Could you please tell me what to do at that times?
