Ya ukhti!

And hold firmly the rope of Allah all together and do not become divided. And remember the favor of Allah upon you- when you where enemies and He brought your hearts together and you became, by His favor, brothers. And you were on the edge of a pit of the Fire, and He save you from it. Thus does Allah make it clear to you His verses that you may be guided. ('Ali 'Imran 3:103)

Once you've given His hidayah, hold it tightly. Don't ever let it go. Maybe, there is no second!!
