the Messenger of Allah said: “There is none who utters a supplication, except that Allah gives him what he asked, or prevents evil from him that is equal to it – as long as he does not supplicate for something evil, or the cutting of ties of the womb.”  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَا مِنْ أَحَدٍ يَدْعُو بِدُعَاءٍ إِلاَّ آتَاهُ اللَّهُ مَا سَأَلَ أَوْ كَفَّ عَنْهُ مِنَ السُّوءِ مِثْلَهُ مَا لَمْ يَدْعُ بِإِثْمٍ أَوْ قَطِيعَةِ رَحِمٍ وَفِي الْبَابِ عَنْ أَبِي سَعِيدٍ وَعُبَادَةَ بْنِ الصَّامِتِ  

The Messenger of Allah said: “Whoever wishes that Allah would respond to him during hardship and grief, then let him supplicate plentifully when at ease.”  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ سَرَّهُ أَنْ يَسْتَجِيبَ اللَّهُ لَهُ عِنْدَ الشَّدَائِدِ وَالْكُرَبِ فَلْيُكْثِرِ الدُّعَاءَ فِي الرَّخَاءِ  

the Messenger of Allah ﷺ said: “The best remembrance is: ‘there is none worthy of worship except Allah (Lā ilāha illallāh)’ and the best supplication is: ‘All praise is due to Allah (Al-ḥamdulillāh).’”  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ أَفْضَلُ الذِّكْرِ لاَ إِلَهَ إِلاَّ اللَّهُ وَأَفْضَلُ الدُّعَاءِ الْحَمْدُ لِلَّهِ  

the Messenger of Allah ﷺ used to remember Allah in all of his affairs.  

كَانَ رَسُولُ اللَّهِ ﷺ يَذْكُرُ اللَّهَ عَلَى كُلِّ أَحْيَانِهِ
