Being well pleased with Allah means to be contented with the fate that Allah has predetermined for one and with what He gives one, unconditionally and encountering no resistance within oneself. One may not realize the goodness in an event at that very moment; but whether one realizes or not, one knows that Allah certainly wills goodness in every event.

In fact, believers always have infinite trust in their Lord in everything that befalls them.

They never wonder whether that event will bring them good or bad, but instead unceasingly trust in Allah and know that they will always find good. 

One may become fatally sick, have a serious accident and become physically disabled, lose all one’s wealth and become poor, be wronged by others or encounter an utterly different unexpected event. No matter what happens, one should know that all these things take place under the complete control of Allah, and therefore feel at peace. That person is completely submitted to Allah’s wisdom and mercy. He gives thanks to his Lord no matter under what the conditions. This is the behavior that a person who is pleased with Allah would exhibit. Allah states the following about His servants who are pleased with Him:

...Allah has inscribed belief upon such people's hearts and will reinforce them with a Spirit from Him and admit them into Gardens with rivers flowing under them, remaining in them timelessly, for ever. Allah is pleased with them and they are pleased with Him. Such people are the party of Allah. Truly it is the party of Allah who are successful. (Surat al-Mujadala,  22)

Drawing Close To Allah?

Drawing close to Allah refers to an enhancement in the love, devotion and fear that a person has for Allah. There is no limit to how near one can draw to Allah. People, in the hereafter, will be repaid in proportion to their nearness to Him and will accordingly earn an eternal life in paradise. Therefore, the real aim of every man in life should be making a sincere effort as Allah proclaims. The efforts made by believers in this respect are pointed out in the Qur’an in these terms:

And among the desert Arabs there are some who believe in Allah and the Last Day and regard what they give as something which will bring them nearer to Allah and to the prayers of the Messenger. It does indeed bring them near. Allah will admit them into His mercy. Allah is Ever-Forgiving, Most Merciful. (Surat at-Tawba, 99) 

 
The love and devotion that a person who has drawn closer to Allah has for Him becomes even more intensified. He greatly fears to act in a way which Allah would not be pleased with and accordingly wards off evil. His devotion to religion, his eagerness and will to serve religion grow stronger. The stronger his closeness to Allah is, the more all these virtues increase.
