A boy called his mother. She replied “yes?”
After little while the son again called his mother. She replied in the same way.
After few minutes the son called his mother again. She replied “I have just now responded for ur call”
The boy again called his mother for the 4th time. Some irritation fell on the mother’s tone, she replied angrily “What?”
The child again called her mother. She replied angrily “Do not irritate me hereafter. I have alot of work”.

At the same time if we call Allah many times in a moment, He won’t be angry with us. Rather His mercy will increase on us. Allah says,
“(O Muhammad), when My servants ask you about Me, tell them I am quite near; I hear and answer the call of the caller whenever he calls Me.” – (QURAN 2:186)

Also if the people call Allah in need, “Angels encompass them, mercy covers them, tranquility descends upon them, and Allah mentions them to those with Him.” – [Tirmidhi]

This is because Allah loves us more than 70 times A mother’s love for her child.
