Ṣadaqah or Saddka (Arabic: صدقة‎, IPA: [sˤɑdæqɐ], "charity", plural ṣadaqāt صدقات) is an Islamic term that means "voluntary charity".

This concept encompasses any act of giving out of compassion, love, friendship (fraternity) or generosity.

Prophet Muhammad said : "We used to sacrifice Atirah in pre-Islamic days during Rajab; so what do you command us?” He said: “Sacrifice for the sake of Allah in any month whatever; obey Allah, Most High, and feed (the people).” (Abu-Dawood : 2824)

"Saddka extinguishes sin as water extinguishes fire." (Tirmidhi : 2541)

"Saddka appeases the Lord’s anger and averts an fire death“”." (Tirmidhi : 1909)

"Give the Saddka without delay, for it stands in the way of calamity." (Tirmidhi: 1887)

"The believer’s shade on the Day of Resurrection will be his Saddka." (Tirmidhi: 1925)

A woman said: "Apostle of Allah, my mother suddenly died; if it had not happened, she would have given Saddka (charity) and donated (something). Will it suffice if I give Saddka on her behalf?" Prophet Muhammad said: "Yes, give Saddka on her behalf." (Abu-Dawood: 2875)

He is the founder and president of the Islamic Research Foundation (IRF), a non-profit organisation that owns the Peace TV channel based in Dubai, UAE. He is sometimes referred to as a televangelist. Before becoming a public speaker, he trained as a doctor. He has written two booklets on Islam and comparative religion. He is regarded as an exponent of the Salafi ideology; he places a strong emphasis on individual scholarship and the rejection of "blind Taqlid", which has led him to repudiate the relevance of sectarian or Madh'hab designations, all the while reaffirming their importance.
