What I like most is " Good, pure speech in this life is a cause of being admitted into Paradise because it is a sign of a good and pure heart. The words that appear on our tongues are only a manifestation of what is in our hearts".. Very true
And it's not easy to have a clean heart.. We r only human..But we can go towards having a clean heart. Nothing can save us in akhirah.. It's all depends on our amal,soleh kids & charity. But again read this : Sesungguhnya perkataan yang baik dan doa buat seseorang muslim lebih baik daripada sedekah yang diikutinya celaan.
