The beauty of the Sunnah

“And whatsoever the Messenger (Muhammad صلى الله عليه وسلم) gives you, take it; and whatsoever he forbids you, abstain (from it)” [al-Hashr 59:7].

The Qur’aan speaks of the importance of the Sunnah
“He who obeys the Messenger has indeed obeyed Allaah . . .” [al-Nisaa’ 4:80]

The Sunnah itself indicates the importance of the Sunnah
Abu Dawud also reported from al-’Irbaad ibn Saariyah, may Allaah be pleased with him, that “the Messenger of Allaah (peace be upon him) led us in prayer one day, then he turned to us and exhorted us strongly . . . (he said), ‘Pay attention to my sunnah (way) and the way of the Rightly-guided Khaleefahs after me, adhere to it and hold fast to it.’” (Saheeh Abi Dawud, Kitaab al-Sunnah).

The scholars’ consensus (ijmaa’) affirming the importance of the Sunnah
Al-Shaafi’i, may Allaah have mercy on him, said: “I do not know of anyone among the Sahaabah and Taabi’een who narrated a report from the Messenger of Allaah (peace be upon him) without accepting it, adhering to it and affirming that this was sunnah. Those who came after the Taabi’een, and those whom we met did likewise: they all accepted the reports and took them to be sunnah, praising those who followed them and criticizing those who went against them. Whoever deviated from this path would be regarded by us as having deviated from the way of the Companions of the Prophet (peace be upon him) and the scholars who followed them, and would be considered as one of the ignorant

It is narrated in al-Saheehayn from ‘Abd-Allaah ibn ‘Amr (may Allaah be pleased with him) that the Prophet (peace and blessings of Allaah be upon him) said: “The best fasting is the fast of Dawood: he used to fast one day and not the next.”

Possible anticancer power in fasting every other day


Fasting every other day reduces some hallmarks of cancer in mice, even when the mice voraciously consume high-fat food between fasts, a study in an upcoming Nutrition shows.

Scientists have known for decades that eating fewer calories — roughly 25 to 50 percent less than recommended — extends life span in animals ranging from worms to dogs. But, “caloric restriction on a daily basis is very hard,” says Eric Ravussin, a physiologist at the Pennington Biomedical Research Center in Baton Rouge, La., who studies caloric restriction.

Last year, researchers including Krista Varady, then of the University of California, Berkeley, published a study suggesting that a less drastic version of caloric restriction provides a constellation of health benefits in mice. Called alternate-day fasting, the regimen of eating as much food, low-fat in this study, as one wants one day but fasting the next confers some of the same anticancer benefits as just cutting calories at a constant rate, the team found.

But for people, eating a low-fat diet one day and fasting the next is still challenging. Varady and her colleagues wanted to know whether the diet could be made easier to swallow and still provide similar benefits.

In the new study, Varady and other researchers compared mice who fasted every other day, both on high-fat and low-fat diets, to mice that didn’t fast but instead ate a low-fat diet every day. The mice on the ultimate yo-yo diet ate high-fat food, in which 45 percent of the calories came from fat — comparable, Varady says, to human diets of fast food and processed food.

On the fasting days, mice were fed 15 percent of their required calories from either the high- or low-fat food.

The results were surprising, says Varady. Mice that ate the rodent equivalent of Big Macs every other day showed the same anticancer benefits of fasting as the mice that ate the low-fat diet every other day. High rates of cell division — a key feature of cancer — were lower in the mice who fasted every other day than in mice that had not fasted. Mice who fasted every other day also had reduced levels of IGF-1, a protein that induces cell growth and has been linked to cancer.

The new study on mice is the “next installment in a systematic and interesting series of studies” from the researchers, comments James Johnson, a doctor affiliated with the Louisiana State University Health Sciences Center and studies alternate-day fasting in humans.

The option to eat high-fat meals while fasting every other day may make people more likely to stick with the demanding diet regimen, researchers say. To date, only three small studies have examined the effects of alternate-day fasting on people, says Varady, now at the University of Illinois in Chicago.

She says the next step is to see whether an unrestricted high-fat diet one day and a small amount of food the next will confer the same health benefits in humans as it does in mice. Varady and her colleagues are currently conducting a study to test whether humans are able to stick with such a diet. Preliminary data suggest that they can.

“The alternate diet has a lot of potential,” comments Valter Longo, a University of Southern California in Los Angeles researcher who studies aging. But, he adds, “I seriously doubt that very many people would adopt it because it is very tough to do regularly.”

Ravussin knows the difficulty firsthand. When he attempted alternate-day fasting himself, he reported feeling very irritable and hungry. “My wife told me, ‘Don’t do it again.’”
