Allah likes that one should keep calling Him

And when a misery touches (such a) man, he calls out to Us whilst lying on his side or sitting or standing. But when We remove from him his affliction, he passes on (forgetting Us) as if he (never) called out to Us in the pain that had touched him. This is how the (wrong) deeds which the transgressors do are made to appear to them fascinating.

Al yunus 12

From this verse ,it is clear that amongst the most noble ones are those who keep calling Allah in their every moment.
Some days ago I came across a compilation of munajaat/duas by Syedna Imam Ali ibn e Talib Karam Allahu wajhu'l kareem ,salamUllahi alaye hi wa RaziAllahu anhu wa an abee hi wa an aalihi.
It was available as Sahifa e Alaviyyah.
Similarly,there is a compilation of munajaat by the son of Syedna Imam Hussain alaye hi salam,Syedna Imam Ali bin hussain a.k.a Imam Zain ul Abideen alaye hi salam.
This compilation also lists very beautiful munajaat and is known as Sahifa e Sajjadiya or Sahifa e Kamila.
We should keep calling Allah while sitting,standing,eating .
Sahifa e Alaviyyah has a very good range of duas.
