“The deeds which Allaah loves most are those done regularly, even if they are small.” Al-Bukhaaree (Sahih al-Bukhari, vol. 3, pp. 108-9, no. 191),
“Small” in number or size. A few regular good deeds are better than many irregular good deeds. That is because regular deeds have a much greater effect on a person’s character. On one occasion a man asked the Prophet (PBUH) about the requirements of Islaam. He outlined the five pillars and then went on to mention the voluntary acts of worship. When the man stated that he would only do the basic compulsory acts without adding to them or decreasing them, the Prophet (PBUH) gave the good news of paradise for him, if he was truthful (Sahih Muslim, vol.1, pp.6-8, no.9).
