In the Name of Allah, the Most Gracious, the Most Merciful
Islam Is Easy
"Invite all to the way of your Lord with Wisdom..." -- Al Qur'an, 16:125
One of the elements of wisdom is that one should not burden people with so much knowledge that people may not understand or remember everything they are taught. Another aspect of wisdom is that people should not be considerate towards each other and not bore them with religious talks all the time, instead there should be a balance and harmony and things should be taught according to time place and people. Thirdly, religion should be made easy, simple and attractive, and it should not be presented as an unaccomplishable task. Remember, Islam is easy!
Sahih Al-Bukhari Hadith -- Hadith 1.68 Narrated by Ibn Masud
The Prophet used to take care of us in preaching by selecting a suitable time, so that we might not get bored. (He abstained from pestering us with sermons and knowledge all the time).
Sahih Al-Bukhari Hadith -- Hadith 1.69 Narrated by Anas bin Malik
The Prophet said, "Facilitate things to people (concerning religious matters), and do not make it hard for them and give them good tidings and do not make them run away (from Islam)."
