PARADISE FOR ALL MANKIND..All humans are brothers and sisters.This was the Motto of Prophet Muhammad sallallahu Alahi Wasallam. He even cried at the death of a Jew. We are his ummati Our concern should be same. To start from ourself reform, family,locality,country to whole mankind till the day of Judgment. Dawah is very effective tool for our correction also.Our success for life here and Hereafter THE LIFE AFTER DEATH is in obeying commands of Allah and following Path of Hazrat Muhammad(PBUH)
Why Allah is not giving Khilafat to Muslim,Precondition is ability of Khilafat
Actually Allah gives Khilafat and Rule so that we should Implement his Shariat and command on the earth.(Surah Al-Nur, Verse 56). When we Muslims are not even implementing the commands of Allah and Path of muhammad sallallahu Alaihi wasallam in our life,for which their is no obstruction/no obstacle in general.
So If he gives us Khilafat Will be able to implement his command on the earth.
So to give Khilafat is very easy for Almighty Allah but We should do our side of the job.
