Islam is the only religion that teaches disciplines(sunnah) in all the activities we do in our day-to-day life from drinking water to using the toilet.None other religions teach us these things. Allah also give us blessings for leading a life in a sunnah manner...Prophet Muhammad (pbuh) said in the following hadith,
"At the time of digression in my Ummah whoever practices my Sunnah, he will get the reward of 100 Martyrs"(Mishqaath).
