It is time for Mahdī (as) to come and clean the dirtiness of the sins in this world. To clean yourself of dirt, it is easy. But an ocean cannot clean the sins inside you. If you repent, Allāh ﷻ will turn your sins into rewards. So don't lose hope. It is a sin to not respect the Prophet ﷺ, because Allāh ﷻ respects him ﷺ and he ﷺ will make shafā‘ah (intercession) for us on the Day of Qiyāmah. Now, some people are rejecting ṭarīqah, sharī‘ah and ḥadīth. ‘Ulamā’ not accepting ḥadīth are kāfir; next they will reject the Qur‘an. It is important to be in the middle, and be with the majority. Those who are not accepting help from Prophet ﷺ can help themselves.
