"O ye who believe! Ward off from yourselves and your families a Fire whereof the fuel is men and stones, over which are set angels strong, severe, who resist not Allah in that which He commandeth them, but do that which they are commanded." [Surah at-Tahrim: 6]
AlhamdulilLah. Ustaz Rahmat completed Chapter 38 on "Urging one's kith and kin to Obey Allah and refrain from evils". Truly, tarbiyah (discipline training) and proper upbringing of kids are essential in order for them to be good citizens of this world and the Hereafter.
Which is why Islam is beautiful - kids are encouraged to pray starting from the age of 7 and they have 3 years to 'play act' on it such that when they reach 10 years old, it would become second nature and a routine in their daily life. It is the amanah (responsibility) of the parents to consistently provide the fundamental religious knowledge and be good role models in practice. Help your kids help themselves in the long run.
Afternote: To bring one who is lost back to the straight path is to encourage him or her to start praying regularly. If one truly contemplates on the surah al-Fateha alone... it is enough to make one humble, grateful for all the ni'mat bestowed upon him or her and to seek help only from Allah SWT. InnalilLahi wa inna ilaihi rojiun (We belong to Allah and to Him we shall return).
