"I had a case of blood flow that was severe and excessive. So I went to the Prophet to inform him and ask him about it. I found him in the house of my sister Zainab bint Jahsh. I said, 'O Messenger of Allah! I suffer from a case of severe and excessive blood flow. So what do you order me to do for it, and does this prevent me from fasting and performing Salat?' He said: 'Tie a cotton rag around yourself and the bIood will go away.' I said, 'It is more than that.' He said: 'Make it tight.' I said, 'It is more than that.' He said: 'Then use a cloth (to bind it).' I said, it is more than that. It flows too much.' So the Prophet said: 'I will order you to do one of two things, which ever of them you do, it will be acceptable for you. You should know which of them you are able to do.' Then he said: 'This is only a blow from Shaitan. Menstruate for six or seven days, which Allah knows, then perform Ghusl. When you see that you have become pure and clean, then perform Salat for twenty-three or twenty-four nights and their days. Perform Salat and fast, and that will be acceptable for you. So do this (if you can) just as (other) women who menstruate and become pure during their periods of menstruation and purity. If (not, and) you are able to delay Zuhr and hasten Asr then perform Ghusl when you have become pure, and pray Zuhr and Asr together. Then delay Maghrib and hasten Isha, then perform Ghusl and combine the two prayers. So do this (if you are able). Then perform Ghusl with the dawn and pray. Do this, and fast if you are able to do so.' Then Allah's Messenger said: 'That is what is preferable to me of the two.'"

Messenger of Allah (PBUH) said, "The first defect (in religion) which affected the Children of Israel in the way that man would meet another and say to him: 'Fear Allah and abstain from what you are doing, for this is not lawful for you.' Then he would meet him the next day and find no change in him, but this would not prevent him from eating with him, drinking with him and sitting in his assemblies. When it came to this, Allah led their hearts into evil ways on account of their association with others." Then he (PBUH) recited, "Those among the Children of Israel who disbelieved were cursed by the tongue of Dawud (David) and 'Isa (Jesus), son of Maryam (Mary). That was because they disobeyed (Allah and the Messengers) and were ever transgressing beyond bounds. They used not to forbid one another from the Munkar (wrong, evildoing, sins, polytheism, disbelief) which they committed. Vile indeed was what they used to do. You see many of them taking the disbelievers as their Auliya' (protectors and helpers). Evil indeed is that which their own selves have sent forward before them; for that (reason) Allah's wrath fell upon them and in torment will they abide. And had they believed in Allah and in the Prophet (Muhammad (PBUH)) and in what has been revealed to him, never would they have taken them (the disbelievers) as Auliya' (protectors and helpers); but many of them are the Fasiqun (rebellious, disobedient to Allah)." (5:78-81)

Then he (PBUH) continued: "Nay, by Allah, you either enjoin good and forbid evil and catch hold of the hand of the oppressor and persuade him to act justly and stick to the truth, or, Allah will involve the hearts of some of you with the hearts of others and will curse you as He had cursed them".

[Abu Dawud and At-Tirmidhi, who categorized it as Hadith Hasan].

The wording in At-Tirmidhi is: Messenger of Allah (PBUH) said, "When the Children of Israel became sinful, their learned men prohibited them but they would not turn back. Yet, the learned men associated with them and ate and drank with them. So, they were cursed at the tongues of Dawud and 'Isa (Jesus), son of Maryam (Mary), because they were disobedient and were given to transgression." At this stage Messenger of Allah (PBUH) who was reclining on a pillow sat up and said, "No, By Him in Whose Hand my soul is, there is no escape for you but you persuade them to act justly."

Salim ibn Jabir al-Hujaymi said, "I came up to the Prophet, may Allah bless him and grant him peace, when he was wrapped up in a cloak whose edges were cover his feet. I said, 'Messenger of Allah, advise me.' He said, 'You must have fearful awareness of Allah. Do not scorn anything correct, even pouring water from your bucket into the bucket of someone else who asks you for water or talking to your brother with a happy face. Beware of dragging your waist-wrapper - it is part of arrogance and Allah does not like it. If a man blames you for something he knows about you, do not blame him for anything you know of him. Leave him to his own evil. You will have your reward. Do not abuse anything.'"

Yahya related to me from Malik that he had heard that Muhammad Sirin used to say, "Do not sell grain on the ears until it is white."

Malik said, "If someone buys food for a known price to be delivered at a stated date, and when the date comes, the one who owes the food says, 'I do not have any food, sell me the food which I owe you with delayed terms.' The owner of the food says, 'This is not good, because the Messenger of Allah, may Allah bless him and grant him peace, forbade selling food until the deal was completed.' The one who owes the food says to his creditor, 'Sell me any kind of food on delayed terms until I discharge the debt to you.' This is not good because he gives him food and then he returns it to him. The gold which he gave him becomes the price of that which is his right against him and the food which he gave him becomes what clears what is between them. If they do that, it becomes the sale of food before the deal is complete."

Malik spoke about a man who was owed food which he had purchased from a man and this man was owed the like of that food by another man. The one who owed the food said to his creditor, "I will refer you to my debtor who owes me the same amount of food as I owe you, so that you may obtain the food which I owe you ."

Malik said, "If the man who had to deliver the food, had gone out, and bought the food to pay off his creditor, that is not good. That is selling food before taking possession of it. If the food is an advance which falls due at that particular time, there is no harm in paying off his creditor with it because that is nota sale. It is not halal to sell food before receiving it in full since the Messenger of Allah, may Allah bless him and grant him peace, forbade that. However, the people of knowledge agree that there is no harm in partnership, transfer of responsibility and revocation in sales of food and other goods."

Malik said, "That is because the people of knowledge consider it as a favour rendered. They do not consider it as a sale. It is like a man lending light dirhams. He is then paid back in dirhams of full weight, and so gets back more than he lent. That is halal for him and permitted. Had a man bought defective dirhams from him as being the full weight, that would not be halal. Had it been stipulated to him that he lend full weight in dirhams, and then he gave faulty ones, that would not be halal for him."
