Prophet Muhammad (may peace be upon him) said: The most excellent fast after Ramadan is God's month. al-muharram, and the most excellent prayer after what is prescribed is prayer during the night (Tahajjud). (Saheeh Al Muslim,Book #006, Hadith #2611).
I want my own Mosque. I will have Eid on a different day. I read Namaz differently. I do my own grieving in Muharram. I don't like you because you are different. I will not tolerate your differences. What is all this? Shias avoid Sunnis for reasons. Sunnis avoid Shias for other reasons. Wahhabis have their own issues. Why? When all have the same Allah, the same Prophet (S.W), the same Quran, the same Kaaba....whose ego are we all satisfying by erecting our own separate mosques?
