How many times the follwoign dua should be read in a day?

Answered according to Hanafi Fiqh by Darulifta-Deoband.com
Sayyiduna Abu Hurayrah (radiyallahu ‘anhu) has said that once he went out with Nabi (sallallahu ‘alayhi wasallam) in a manner that his hand was Nabi (sallallahu ‘alayhi wasallam)’s hands. He passed by a person who was disheveled and worried. He asked, ‘What brought you to this condition?’ That person said, “Sickness and poverty have done this to me.” He said, “I am going to tell you a few words. If you recite these, your sickness and poverty will go away. The words were:

تَوَكَّلْتُ عَلَى الْحَيِّ الَّذِي لا يَمُوتُ ، وَالْحَمْدُ لِلَّهِ الَّذِي لَمْ يَتَّخِذْ وَلَدًا ، وَلَمْ يَكُنْ لَهُ شَرِيكٌ فِي الْمُلْكِ ، وَلَمْ يَكُنْ لَهُ وَلِيُّ مِنَ الذُّلِّ ، وَكَبِّرْهُ تَكْبِيرًا.
Can we read this dua any number of times or only once in a day? I mean can I recite it 500 times or more times in a day or only once in a day?

بسم الله الرحمن الرحيم

(Fatwa: 654/492/SN=5/1439)

This dua is recorded in Musnad Abu Ya’la, Amal al-Yaum wa al-Lailah and Majma al-Zawaid but nowhere the number is mentioned. However, some narrations make it clear that the person continued reading the dua till his condition got better. So you should also read this dua as and when you find time extensively. However, if you fix some quantity such as ten, twenty or hundred times on daily basis then there is no harm in it.

Allah knows Best!
