Man's love for Allah is all about striving hard to uphold His Deen and obedience to Him, His Messenger or any system or authority that implements His Rule. In return, Allah's love for man is  about being Gracious and Beneficent to man and providing him protection  from the harmful consequences of his shortcomings or inadvertent mistakes [See, 3:31-32, 5:54, 9:24]. In the Quran, various types of people are mentioned whom Allah  loves, i.e. who get blessed with His special grace, beneficence and protection.

Allah loves Muhsineen [2:195, 3:134, 3:148, 5:13, 5:93] [Those who do good (to others); who spend (benevolently) in the cause of Allah (2:195) in favorable as well as in adverse circumstances; who divert and sublimate their anger and potentially virulent emotions to creative energy and become a source of tranquility and comfort to people; who quickly correct any wrong or indecency that has occurred from them, remember Allah,  protect themselves from trailing behind in dignity and refrain from willfully persisting in error. [3:134-135]; who pardon and forbear [5:13]; who do not spread corruption on earth  [7:56];  who strive hard for Him [29:69];  who establish As-Salaat [remembering Him (20:14, 62:9) all the time (70:23) and at appointed times (4:103, 62:9), and follow His Guidance in all the affairs] and keep the resources, that He has bestowed upon them, open [for the welfare of humanity]. (2:177, 9:44, 39:33, 92:17-20) [31:3-4]; who are the believing servants of Allah [37:110-111, 37:121-122, 37:131-132]; who sleep but little at night (reflecting on His Commands and on ways to implement His Commands) and heartily seek to be guarded against imperfections (51:16-18)].

(2:177, 9:44, 39:33, 92:17-20) [31:3-4]; those who give from their wealth to family and relatives, orphans, widows to those left helpless in the society, to those whose hard-earned income fails to meet their basic needs, to those whose running businesses have stalled, to those who have lost their jobs, to the one whose life has stalled for any reason, to the disabled, the needy wayfarer, son of the street, the homeless, the one who travels to them for assistance, to those who ask for help, and to those whose necks are burdened with any kind of bondage, oppression, crushing debts and extreme hardship of labour [2:177]; those who spend their wealth for their own tazkiya or personal development and not for favour from anyone to be paid back [92:17-20]; those who are true to their promises and covenants whenever they make a promise or covenant [2:177, 8:56, 9:4, 9:7]; those who remain steadfast in physical or emotional distress and in times of peril [2:177]; those who avoid great sins and fawahish (yet not ascribe purity to themselves) [53:32]; those who promote the truth and believe therein [39:33]; those who remember Allah immediately, when approached by devil [7:201]; those who strive in the way of Allah by their wealth and lives [9:44]; and those who will be in the pure state when Angels come to take their lives [16:31-32]
