Surah Yasin (36)
Ma’qil Ibn Yasar (radiAllahu anhu) reported that the messenger of Allah (salAllahu alayhi wasalam) said ‘Whoever reads Ya Sin, seeking Allah’s pleasure, his past sins will be forgiven, so recite it over the dying among you’
[Bayhaqi]
Abu Hurairah (radiAllahu anhu) narrated that the messenger of Allah (salAllahu alayhi wasalam) said, ‘Whoever reads surat Ya-Sin in the night, he will be forgiven. And whoever reads Ha-Meem, the one in which smoke is mentioned, he will be forgiven.’
[Abu Ya’la reported it]
Anas (radiAllahu anhu) reported that the messenger of Allah (salAllahu alayhi wasalam) said ‘Everything has a heart and the heart of the Qur’an is Ya Sin. Anyone who reads it, God will write down for him ten readings of the Qur’an’
