as-salaamu 'alaikum wa rahmatullaahi wa barakaatuh,
Allah said in His Book:
فَاعْلَمْ أَنَّهُ لَا إِلَٰهَ إِلَّا اللَّهُ وَاسْتَغْفِرْ لِذَنبِكَ
{So know (O Prophet) that La ilaha ill-Allah (none has the right to be worshipped but Allah), and ask forgiveness for your sin ...}
And based on this verse, Imaam al-Bukhaari (may Allah have mercy upon him) - and the Scholars in general - explain: "العلم قبل القول والعمل " (i.e. that Knowledge precedes Speech & Action).
Based on the above it is important that as the Blessed Month of Ramadan - the Month of Fasting - approaches, we study & learn what Allah has prescribed for us in this month - so that we can, insha'Allah, worship Him upon baseerah (clear insight) and so He accepts our acts of worship from us. In this regard, below are some links to some beneficial resources I hope would benefit my brothers & sisters in Islaam.
I ask Allah that He help us reach the month upon Taqwaa, bless us with much righteous actions in it, accept it all from us and grant us a great reward for it - for indeed He is Jawwaad, Kareem.
