Abu Hurayra reported that the Prophet, may Allah bless him and grant him peace, said, "Allah is angry with someone who does not ask of Him."  

عَنِ النَّبِيِّ ﷺ قَالَ مَنْ لَمْ يَسْأَلِ اللَّهَ غَضِبَ اللَّهُ عَلَيْهِ  

Anas reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "When you call on Allah, be definite in your supplication. None of you should say, 'If You will, give it to me.' No one can force Allah."  

قَالَ رَسُولُ اللهِ ﷺ إِذَا دَعَوْتُمُ اللَّهَ فَاعْزِمُوا فِي الدُّعَاءِ وَلاَ يَقُولَنَّ أَحَدُكُمْ إِنْ شِئْتَ فَأَعْطِنِي فَإِنَّ اللَّهَ لاَ مُسْتَكْرِهَ لَهُ  

'Uthman said that he heard the Prophet, may Allah bless him and grant him peace, say, "A person will not be harmed by anything if he says every morning and evening 33 times, 'In the Name of Allah by whose Name nothing in the earth or the heaven is harmed. He is the All-Hearing, the All-Knowing.'"  

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ مَنْ قَالَ صَبَاحَ كُلِّ يَوْمٍ وَمَسَاءَ كُلِّ لَيْلَةٍ ثَلاَثًا ثَلاَثًا بِسْمِ اللهِ الَّذِي لاَ يَضُرُّ مَعَ اسْمِهِ شَيْءٌ فِي الأَرْضِ وَلاَ فِي السَّمَاءِ وَهُوَ السَّمِيعُ الْعَلِيمُ لَمْ يَضُرَّهُ شَيْءٌ
