(from http://ikhwah.com/unity/precious.html)
I have been advocating the Unity of the Ummah. I have outlined the disadvantages and harm the nation is being made to suffer because of the disunity. I can and also many people can enumerate the advantages and benefits the ummah will reap, if it gets united.
But here is a verse from Qur-aan which tells us what is in store for us, if we remain divided and in dispute :
"And be you not like those who (got) divided and disputed after the clear proofs had come unto them. For such there is an awful doom," (3:105) To the Muslims of the times when this verse of Qur-aan descended, this warning from Allaah was of no immediate concern, because they were all united. But today, we have to ask ourselves whether or not we come under the ambit of the threat which the verse carries; Are we not divided and in dispute? Then, are we not subject to the same threat of an awful doom? When would we open the eyes of our hearts to the reminders from Allaah?
