Three important and beneficial things:
1) Hazrat Muhammad s.a.w.(PBUH) says that 'if a person recite ' Ayatal Kursi' after every Farz Namaz then there will be nothing between him and Heaven except Death'
2) There is a Hadith that says 'La Haula Wala Quuata illa billahilaliyul azeem' is such a great medicine that it cures every disease and the most minor disease it cures is 'Sorrow' (Gham).
3) Another Hadith says 'if a person recite surah ikhlaas (QUL huwallahuahad... ) 10 times in a day then Allah build a palace for him in the Heaven.(Subhaan Allah)'
How simple it is to get such lavish rewards! MashAllah!
