1) why is maulidur Rasul not an ibadah when what you are doing is only selawat/having islamic talks???
2) if u say it is bid'ah and not ibadah, then to celebrate ur children's birthday is bid'ah as well & u say u follow Q & S, well is celebrating ur child's birthday stated in the Quran nor a Sunnah (done by Rasulullah)??
3) even so, bid'ah has two types. hasanah (good - does not oppose Q & S) and sayi'ah (bad - opposes Q & A). in anyway does Maulidur Rasul opposes Q & S? it depends on how u do it actually.
"And we ordained in the hearts of those who followed him Compassion and Mercy. But the Monasticism which they innovated for themselves which we did not prescribe for them"
Surah Al Hadeed, verse 27"
This verse points out that when something new is invented to please Allah Ta'ala then it is permissible, and Allah Ta'ala gives reward for it. Those who do not fulfil the requirements then Allah Ta'ala will not reward them.
Rasulullah [May Allah bless Him and grant Him peace] stated: "The person who introduced a good thing in Islam, shall obtain the reward for it and also the reward for those who adopt it. As for the one who introduces a bad thing (Bid'ah Sayyi ah) he will obtain the punishment for introducing it and also for those who adopt it, will also be punished."
(Sahih Muslim in Kitaab-uz-Zakaat Tirmidhee chapter Eleleven).
