Q: There are many hadiths which speak about how the shirk that the Sahaba used to do before accepting Islam such as worshipping idols and their other sins have been forgiven once they accepted Islam and became Muslims. Obviously, anyone who was never a Muslim before will be forgiven no matter what did they did in the past once they become Muslims because they didn't know about Islam before. But are there any authentic hadiths which talk about a Muslim committing shirk and being forgiven by Allah even after being a Muslim. Are there any hadiths about a person who is a Muslim and leaves Islam by committing Shirk but Allah still forgives him. I don't think I came across any hadith that speaks about a Muslim being forgiven for shirk, only for non-muslims being forgiven for shirk once there Muslim. Can you give me an authentic hadith that say Allah forgives a Muslim who does shirk and also verses from the Quran if it says this? I'm specifically talking about a Muslim who does shirk and is forgiven, not a non-muslim who does shirk and is forgiven when he accepts Islam. Please give me any references that specifically says this.

Q: My locality had a whole weekend (13-15/2/2015) program in celebration of the moulood of Rasulllah (Sallallahu Alayhi Wasallam). I am aware of the "over importance" given to this as it is considered an innovated matter in the religion but do you know why this weekend in particular? Also the speaker mentioned that he would rather want to be seen to support Hussain (Radiyallahu Anhu) than Yazid. Can you also explain/clarify if delaying the athaan and jamaat salaah for other religious activities like lectures and naats etc is permissible. Then the masjid was heavily "decorated" with banners and flowers. Is this permissible? The people are known as Sunnis. Please advise.
