"O you who believe, fasting has been prescribed for you as it was prescribed for people before you so that you attain Taqwa.” (Q2:183)

"The month of Ramadhan [is that] in which was revealed the Qur'an, a guidance for the people and clear proofs of guidance and criterion. Therefore, whoever sights [the new moon of] the month, let him fast it, and whoever is ill or on a journey - then an equal number of other days. Allah intends for you ease and does not intend for you hardship and [wants] for you to complete the period and to glorify Allah for that [to] which He has guided you, and perhaps you will be grateful." -- Surat Al-Baqarah 2:185

"Allah has made Laylat al-Qadr in this month, which is better than a thousand months, as Allah says...The Night of Al-Qadr is better than a thousand months. Therein descend the angels and the Rooh [Jibreel (Gabriel)] by Allah’s Permission with all Decrees, there is peace until the appearance of dawn." -- Al-Qadar 97:1-5

Laylat-ul-Qadr is the prized jewel of Ramadan. This night carries more blessings than a thousand months. Muslims spend this night in prayer and meditation.
