Allāh said:
﴿ إِنَّ اللَّهَ وَاسِعٌ عَلِيمٌ ﴾
“Indeed, Allāh is All-Encompassing/Vast (Wāsiʿ), All-Knowing” [Al-Baqarah: 115].
And Allāh said:
﴿ وَاللَّهُ وَاسِعٌ عَلِيمٌ ﴾
“And Allāh is All-Encompassing/Vast (Wāsiʿ), All-Knowing” [Al-Baqarah: 247].
And Allāh said:
﴿ رَبَّنَا وَسِعْتَ كُلَّ شَيْءٍ رَحْمَةً وَعِلْمًا ﴾
“Our Lord, You have encompassed all things in mercy and knowledge” [Ghāfir: 7].
Shaykh al-Sa’dī said: He is The One who is vast with respect to His Attributes and qualities and those things linked to them this from the point of view that none can enumerate His praise as He deserves, rather He is as He has praised Himself. Vast in grandeur, authority and dominion, vast in bestowing grace and good, great in majesty and nobility. (Explanation to the Beautiful and Perfect Names of Allāh pg. 95, Dar as Sunnah print, Taysīr al-Karīm al-Rahmān 5/305)
Shaykh al-‘Uthaymīn said: Al-Wāsiʿ means vast in encompassment, and vast in attributes, so He is vast in His knowledge, and in His power, and His Hearing and His Seeing, and other attributes of His. (Tafsīr Thamanīn 1/195)
Al-Tabarī said: “Wāsiʿ”: He encompasses all His creation with sufficiency, bounty, generosity and management. (Tafsīr Al-Tabarī 3/984)
Ibn Qutaybah said: “Among His attributes is ‘Al-Wāsiʿ,'” and it means The-Rich/Self-Sufficient (i.e. in need of none, whilst all else is needy), and “al-sa’ah” (السعة) means wealth. (Tafsīr Gharīb al-Qurān pg. 46)
Al-Azharī said: Al-Wāsi’ – among the attributes of Allāh The Most-High: He whose provision encompasses all His creation, and whose mercy encompasses everything. (Mu’jam al-Tahdhīb al-Lughā 4/3889)
Al-Kalbī said: “Indeed, Allāh is All-Encompassing/Vast (Wāsiʿ), All-Knowing” (2:115) means “vast in Forgiveness.” (Tafsīr al-Baghawī 1/140)
Ibn al-Anbārī said: “Al-Wāsiʿ” among Allāhs names means: “The One abundant in giving, who has capacity for what is asked of Him.” (Mu’jam al-Tahdhīb al-Lughā 4/3890)
Al-Wāhidī said: He is All-Encompassing/Vast in His bounty upon His creation, and in His tolerance of His servants’ requests, and the persistence of their asking does not trouble Him (Tafsīr al-Basīt 3/235)
Al-Rāghib Al-Asfahānī: “And His saying: ‘My Lord has encompassed all things in knowledge’ is a description of Him, like: ‘He has encompassed all things in knowledge,’ and His saying: ‘And Allāh is All-Encompassing/Vast, All-Knowing,’ and ‘Allāh is All-Encompassing/Vast, All-Wise,’ expresses the vastness of His Power, Knowledge, Mercy, and Bounty” (al-Mufradāt 211)
‘Abdul-‘Azīz al-Humaydī said: Allāh is Al-Wāsiʿ, who multiplies reward and recompense for His servants many times over, as He said:
﴿ مَثَلُ الَّذِينَ يُنفِقُونَ أَمْوَالَهُمْ فِي سَبِيلِ اللَّهِ كَمَثَلِ حَبَّةٍ أَنبَتَتْ سَبْعَ سَنَابِلَ فِي كُلِّ سُنبُلَةٍ مِّائَةُ حَبَّةٍ وَاللَّهُ يُضَاعِفُ لِمَن يَشَاءُ وَاللَّهُ وَاسِعٌ عَلِيمٌ ﴾
Allāh is Al-Wāsiʿ whose bounty and generosity are in His Hand; He gives His bounty to whom He wills among His servants, as He said:
“The example of those who spend their wealth in the way of Allāh is like a seed [of grain] which grows seven spikes; in each spike is a hundred grains. And Allāh multiplies [His reward] for whom He wills. And Allāh is All-Encompassing/Vast, All-Knowing” [Al-Baqarah: 261].
﴿ قُلْ إِنَّ الْفَضْلَ بِيَدِ اللَّهِ يُؤْتِيهِ مَن يَشَاءُ وَاللَّهُ وَاسِعٌ عَلِيمٌ ﴾
“Say, ‘Indeed, [all] bounty is in the hand of Allāh – He grants it to whom He wills. And Allāh is All-Encompassing/Vast, All-Knowing'” [Āl ‘Imrān: 73]. (Rawāih al-Husnā pg. 248-249)
