We need to prepare for the month of Ramadan like we need to prepare for many large events in life. We know it is coming and we must be ready.
Even non-Muslims understand that Muslims will not be around much during Ramadan. This is because it is such a holy month and we put so much dedication into it.
We have to start preparing from now to gain the blessings of Ramadan as well as after Ramadan.
Mufti Menk has this wonderful talk about preparing for the holy month!
