Shaikh Khidir from Toronto, Canada once gave a very beautiful example on the importance of following the ways (sunnah) of Prophet Muhammad (peace be upon him). He said that sunnah is like medicine. Usually, when we visit the doctors for treatment, they write on the prescriptions the medicines we need. We take these prescriptions to pharmacists who then sell the medicines to us. Sometimes these medicines are bitter and hard to swallow, but we still consume them as we know that the cure is in them. Similarly, each and every sunnah has physical and spiritual cure for us in this world and in the hereafter. Even if some of sunnah are hard to follow, we should still follow them as the cure is in them.
"...So take what the Messenger gives you, and refrain from what he prohibits you..." Al Quran 59:7
