Waad: meaning of the name

وَٱذْكُرْ فِى ٱلْكِتَٰبِ إِسْمَٰعِيلَ إِنَّهُۥ كَانَ صَادِقَ ٱلْوَعْدِ وَكَانَ رَسُولًا نَّبِيًّا ۝٥٤

And mention in the Book, Ishmael. Indeed, he was true to his promise, and he was a messenger and a prophet.

Surah Maryam, Verse 54

وَعْدَ ٱللَّهِ لَا يُخْلِفُ ٱللَّهُ وَعْدَهُۥ وَلَٰكِنَّ أَكْثَرَ ٱلنَّاسِ لَا يَعْلَمُونَ ۝٦

[It is] the promise of Allāh. Allāh does not fail in His promise, but most of the people do not know.

Surah Ar-Rum, Verse 6

يَٰٓأَيُّهَا ٱلنَّاسُ ٱتَّقُوا۟ رَبَّكُمْ وَٱخْشَوْا۟ يَوْمًا لَّا يَجْزِى وَالِدٌ عَن وَلَدِهِۦ وَلَا مَوْلُودٌ هُوَ جَازٍ عَن وَالِدِهِۦ شَيْـًٔا إِنَّ وَعْدَ ٱللَّهِ حَقٌّ فَلَا تَغُرَّنَّكُمُ ٱلْحَيَوٰةُ ٱلدُّنْيَا وَلَا يَغُرَّنَّكُم بِٱللَّهِ ٱلْغَرُورُ ۝٣٣

O mankind, fear your Lord and fear a Day when no father will avail his son, nor will a son avail his father at all. Indeed, the promise of Allāh is truth, so let not the worldly life delude you and be not deceived about Allāh by the Deceiver [i.e., Satan].

Surah Luqman, Verse 33

وَلَقَدْ صَدَقَكُمُ ٱللَّهُ وَعْدَهُۥٓ إِذْ تَحُسُّونَهُم بِإِذْنِهِۦ حَتَّىٰٓ إِذَا فَشِلْتُمْ وَتَنَٰزَعْتُمْ فِى ٱلْأَمْرِ وَعَصَيْتُم مِّنۢ بَعْدِ مَآ أَرَىٰكُم مَّا تُحِبُّونَ مِنكُم مَّن يُرِيدُ ٱلدُّنْيَا وَمِنكُم مَّن يُرِيدُ ٱلْـَٔاخِرَةَ ثُمَّ صَرَفَكُمْ عَنْهُمْ لِيَبْتَلِيَكُمْ وَلَقَدْ عَفَا عَنكُمْ وَٱللَّهُ ذُو فَضْلٍ عَلَى ٱلْمُؤْمِنِينَ ۝١٥٢

And Allāh had certainly fulfilled His promise to you when you were killing them [i.e., the enemy] by His permission until [the time] when you lost courage and fell to disputing about the order [given by the Prophet (ﷺ)] and disobeyed after He had shown you that which you love. Among you are some who desire this world, and among you are some who desire the Hereafter. Then He turned you back from them [defeated] that He might test you. And He has already forgiven you, and Allāh is the possessor of bounty for the believers.

Surah Ali ’Imran, Verse 152
