I am a Haafiz, however due to a flatulence problem I am unable to keep wudhu for long, hence I am deprived of leading the Taraaweeh Salaat.

Answer

The objective of Hifz is not to lead Taraaweeh Salaat. Hifz is for Allah's Pleasure and thawaab in the Aakhirah. Your dejection is because your niyyat for pursuing Deeni Ilm is improper and corrupt. The intention of your parents too is corrupt. Riya and takabbur will deprive them of the wonderful crown of Noor promised for the parents of a Haafiz on the Day of Qiyaamah. Your niyyat of Deeni service is also corrupt. This intention for pursuing Ilm is not correct. The purpose of Knowledge is to be able to practise the Deen correctly for Allah's Sake and for salvation in the Aakhirah. The 'deeni service' motive is a trick of shaitaan. Only those upon whom Allah Ta'ala thrusts Deeni service are able to serve the Deen constructively with Ikhlaas. All the other self-appointed, self-hoisted so-called 'deeni' servants are flotsam and they soon turn into agents of Iblees.

For your flatulence problem, you have to drastically change your diet. See a hakeem or a naturopath who will prescribe a proper diet.
