Hadith: The Messenger of Allah (may Allah's peace and blessings be upon him) would strive more in Ramadan than he would strive in other than it, and in the last ten of it than he would strive in other than them

عن عائشة رضي الله عنها قالت: كان رسول الله صلى الله عليه وسلم يَجْتَهِدُ في رمضان ما لا يَجْتَهِدُ في غيره، وفي العَشْرِ الأوَاخِرِ منه ما لا يَجْتَهِدُ في غيره.
[صحيح] - [رواه مسلم]

‘Ā’ishah (may Allah be pleased with her) reported: 'The Messenger of Allah (may Allah's peace and blessings be upon him) would strive more in Ramadan than he would strive in other than it, and in the last ten of it than he would strive in other than them.
Sahih/Authentic. - [Muslim]

Explanation

In this Hadīth, ‘Ā’ishah tells about the Prophet's worship in the month of Ramadan. He would work harder in Ramadan than in other months, because it is a blessed month. Allah made it superior to other months. During the ten nights of it, the Prophet would strive even harder than he would at the beginning of the month, because the Night of Decree is in one of these ten nights. This night is better than one thousand months, and because it comes at the end of this blessed month, the Prophet wanted to conclude his worship with good deeds in it.
