Ibraaheem An-Nakha’ee [rahimahullaah] said:

”The people are destroyed by excess wealth and speech” [Jaami-ul Uloom Wal-Hikam: page:144]

Muhammad Bin Ajlaan [rahimahullaah] said:

”Indeed, speech is four [types]: [a] you remember Allaah; [b]Recite the Qur’aan; [c] You are asked about an affair of knowledge, so you give information about it; [d] or you speak about an affair of the worldly life that concerns you.” [Jaami-ul Uloom Wal-Hikam: page:144]
