How can one overcome the whispers of Satan and focus on prayer and overcome excessive absentmindedness in it?

Qiyam al-Layl (night prayer) is among the traditions of the Prophets and the practice of the righteous. One must strive to maintain it as much as possible, preparing for it psychologically by using the siwak, performing wudu thoroughly, wearing the best clothes, and having the intention of standing before Allah and supplicating Him. It should not be delayed until one gets bored of watching television, because excessive viewing deadens the heart, makes one forget the Book of Allah, and diminishes humility. It is recommended to reduce television viewing or limit it to important and religious programs.
