The questioner:
The issue of the matter is delayed beyond the extent of forgetfulness between taking and harm, so they said that if it is with that matter, then he must choose it.
The Shaykh:
And the Prophet (peace and blessings be upon him), when he was fasting on Mondays and Thursdays and not fasting one day and breaking the fast one day, was seeking to make things easy for the Ummah because he is a role model. If he had fasted one day and broken the fast one day, that would have been difficult for the people. And he (peace and blessings be upon him) was seeking to make things easy for the Ummah.Sunan Abi Dawud 47Sahih (Al-Albani) In a narration, [it is mentioned] with every ablution, and he (peace and blessings be upon him) was considering making things easy for the Ummah. He used to leave off an action that he loved to do, out of fear of hardship for the Ummah, because he is a role model, peace and blessings be upon him.

Were it not hard on my ummah, I would order them to use the tooth-stick at the time of every prayer.
