Narrated ‘Aisha (May Allah be pleased with her):
The Messenger of Allah (salAllahu alayhi wa sallam) never fasted in any month more than in the month of Shaban.
He used to say: “Do those deeds which you can do easily, as Allah will not get tired (of giving rewards) till you get bored and tired (of performing religious deeds).”
The most beloved prayer to the Prophet was the one that was done regularly (throughout the life) even if it were little. And whenever the Prophet offered a prayer he used to offer it regularly.
[Sahih Bukhari Book 31, Hadith 191]
