Du'a for seeking well-being and being thankful

He said that once `Ali b. al-Husayn (a) saw a person doing tawaaf of al-Ka`bah and saying: O God I ask from You the patience (as-Sabr).
The Imam striked his shoulder and said: you have asked for affliction (balaa'),

[Instead] say: Allaahumma innee as-alukal-`aafiyah, wash-shukra `alal-`aafiyah.
O Allah I ask from You the well-being, and to be grateful for the well-being.
