Taqwaa is not by praying all night and fasting all day but rather it is abiding by the commands of Allah and staying away from His prohibitions.
UmarTo be alone means that you avoid bad company. But to have a true friend is better than being alone.
UmarI looked at all friends, and did not find a better friend than safeguarding the tongue. I thought about all dresses, but did not find a better dress than piety. I thought about all types of wealth, but did not find a better wealth than contentment in little. I thought of all types of good deeds, but did not find a better deed than offering good advice. I looked at all types of sustenance, but did not find a better sustenance than patience.
Umar
