"We are a trial, so do not disbelieve [by practicing magic]." And
[yet] they learn from them that by which they cause separation between a man
and his wife. But they do not harm
anyone through it except by permission of Allah. And the people learn what

11:13-14 - "Or do they say, "He invented it"? Say, "Then bring ten surahs like it that have been invented and call upon [for assistance] whomever you can besides Allah, if you should be truthful."

And Allah is Knowing and Wise.”
Tafsir ibn Kathir – “Al-Mu'allafatu Qulubuhum There are several types of Al-Mu'allafatu Qulubuhum. There are those who are given alms to embrace Islam... Some of Al-Mu'allafatu Qulubuhum is given from alms so that they become better in Islam and their heart firmer in faith... Some people are given because some of his peers might embrace Islam, while others are given to collect alms from surrounding areas, or to defend Muslim outposts.” http://www.qtafsir.com/index.php?option=com_content&task=view&id=2543&Itemid=64

And you feared the people, while Allah has more right that you fear Him. So when Zayd had no longer any need for her, We married her to you in order that there not be upon the believers any discomfort concerning the wives of their adopted sons when they no longer have need of them. And ever is the command of Allah accomplished.”
33:50 – “...a believing woman if she gives herself to the Prophet [and] if the Prophet wishes to marry her, [this is] only for you, excluding the [other] believers...”

Then they will nod their heads toward you and say, "When is that?" Say, "Perhaps it will be soon –“
44:34-37- “Indeed, these [disbelievers] are saying, There is not but our first death, and we will not be resurrected. Then bring [back] our forefathers, if you should be truthful.”
45:24-26- “And they say, "There is not but our worldly life; we die and live, and nothing destroys us except time." And they have of that no knowledge; they are only assuming. And when Our verses are recited to them as clear evidences, their argument is only that they say, "Bring [back] our forefathers, if you should be truthful." Say, "Allah causes you to live, then causes you to die; then He will assemble you for the Day of Resurrection, about which there is no doubt, but most of the people do not know."
