Allah (swt) becomes angry when he is not asked. Whilst man becomes annoyed when he’s constantly sought.

The Prophet (saws) said:

مَنْ لَمْ يَسْأَلِ اللَّهَ يَغْضَبْ عَلَيْهِ

“Whoever does not ask from Allah, Allah becomes angry with him” (Al-Tirmidhi).

Persistence in du’a is actually a noble trait and from good adab with Allah.

Why? For two reasons:

1) Because you are displaying your neediness to Allah. This is a form of humility.

2) You are affirming that it is only Allah who can fulfil your request. This is recognising him as al-Razzaq and al-Wahhaab, the sole Provider and Bestower.

Summary: Allah loves to be asked, so continuously ask him.
