It is reported in a hadith that Prophet Sallahoalaihewassallam has said
“أَحَبُّ الأعمالِ إلى اللهِ أدومُها و إن قل“
Allah taala’s most admiring deeds are those which are consistently performed though they are fewer in numbers.
Shaikh ul Hadith Hazrat Maulana Jalil Ahmed Akhoon sb elaborates that this is regarding non-obligatory deeds (nawafil)
One should not be too much concerned about the amount of nafils, tahajjud, recitation, etc. Rather, one should try to be consistent, no matter fewer in cpunts, in performing these deed. This way good deeds will be psychologically easier to perform and will accumulate over time.
We see people reciting Quran for few specific days and nights and then forget the recitation for months. Similarly, people perform some good deeds on specific dates for the benefit of the loved ones who have passed away but completely forget them for a year.
My shaikh Hazrat Maulana Jalil Ahmed Akhoon sb damat barakatuham used to say that daily recitation of as fewer as 2 ayaat has been promised in a hadith with glad tidings.
We often defer our charity, zikr, recitation, and wait for substantial amount of funds, time, and tranquility. This approach is inaccurate and this wait is futile. Why should we wait when the Prophet sallallaho alaihi wassalam and his companions did not waited for tranquility and affluence and started whatever they could in whatever situations they were in.
In essense one should practise such nafil deeds that he/she could perform consistently, no matter how small they are.
