I Would Have Ordered Them To Clean Their Teeth With Siwak…

Narrated Abu Huraira (may ALLAH be pleased with him):

ALLAH's Apostle (peace and blessings of ALLAH be upon him) said:
"If I had not found it hard for my followers or the people, I would have ordered them to clean their teeth with siwak for every prayer."

[Sahih Bukhari (Book #13, Hadith #12)]
