*Fighting over the number of Rakaah of Taraweeh
There is no specific number of rak'ahs for Taraweeh prayer, rather it is permissible to do a little or a lot. Both 8 and 20 are okay.
Shaykh Ibn 'Uthaymeen said:
"No one should be denounced for praying eleven or twenty-three (raka'ah), because the matter is broader in scope than that, praise be to Allaah."
*Praying ONLY on the night of the 27th
Some people pray ONLY on the 27th to seek Lailat ul-Qadr, neglecting all other odd nights, although the Prophet (Sal Allaahu Alaiyhi wa Sallam) said:
"Seek Lailat ul-Qadr among the odd numbered nights of the last ten nights of Ramadaan." (Bukhaari, Muslim).
*Wasting the last part of Ramadaan preparing for Eid
Some people waste the entire last 10 days of Ramadaan preparing for Eid, shopping and frequenting malls, etc. neglectingIbadah and Lailatul Qadr. although, the Prophet (Sal Allaahu Alaiyhi wa Sallam) used to strive the hardest during the last ten days of Ramadaan in worship (Ahmad, Muslim) and not in shopping. Buy whatever you need for Eid before Ramadaan so that you can utilize the time in Ramadaan to the max.
Aa’ishah (RA) said:
“When the (last) ten nights began, the Messenger of Allaah (Sal Allaahu Alaiyhi wa Sallam)) would tighten his waist-wrapper (i.e., strive hard in worship or refrain from intimacy with his wives), stay awake at night and wake his family.”
(Bukhaari and Muslim).
*Iftaar parties
Although inviting each other for breaking fast is something good and encouraged, some people go to extremes with lavish 'Iftaar parties' with all sorts of disobedience to Allaah, from flirting, mixing of the sexes and hijaab-less women, to show-off and extravagance, to heedlessness to Salaah, and Taraweeh to even music and dancing.
*Taking Ramadaan as a ritual
For many of us Ramadaan has lost its spirituality and has become more of a ritual than a form of Ibaadah. We fast from morning to night like a zombie just because everyone around us is fasting too. We forget that its a time to purify our hearts and our souls from all evil....we forget to make dua, forget to beseech Allaah to forgive us and ask Him to save us from the Fire. Sure we stay away from food and drink but that's about all.
*Although the Prophet (Sal Allaahu Alaiyhi wa Sallam) said:
“Jibreel said to me, ‘May Allaah rub his nose in the dust, that person to who Ramadaan comes and his sins are not forgiven,’ and I said, ‘Ameen’. Then he said, ‘May Allaah rub his nose in the dust, that person who lives to see his parents grow old, one or both of them, but he does not enter Paradise (by not serving them)’ and I said, ‘Ameen’. Then he said,‘May Allaah rub his nose in the dust, that person in whose presence you are mentioned and he does not send blessings upon you,’ and I said, ‘Ameen.’” (Tirmidhi, Ahmad, others. Saheeh by al-Albaani)
*Too much stress on food and drink
For some people, the entire month of Ramadaan revolves around food. They spend the ENTIRE day planning, cooking, shopping and thinking about only food, instead of concentrating on Salaah, Quraan and other acts of worship. All they can think of is FOOD. So much so that they turn the month of 'fasting' into the month of 'feasting'. Come Iftaar time, their table is a sight to see, with the multitudes and varieties of food, sweets and drinks. They are missing the very purpose of fasting, and thus, increase in their greed and desires instead of learning to control them. It is also a kind of waste & extravagance.
".....and eat and drink but waste not by extravagance, certainly He (Allaah) likes not Al-Musrifoon (those who waste by extravagance) " [al-Araaf :31]
*Spending all day cooking.
Some of the sisters (either by their own choice or forced by their children/ husbands) are cooking ALL day and ALL night, so that by the end of the day, they are too tired to even pray Ishaa, let alone pray Taraweeh or Tahajjud or even read Quraan. This is the month of mercy and forgiveness. So turn off that stove and turn on your Imaan!
*Eating too much
Some people stuff themselves at Suhoor until they are ready to burst, because they think this is the way to not feel hungry during the day and some people eat at Iftaar, like there is no tomorrow, trying to 'make up for the food missed.' However, this is completely against the Sunnah. Moderation is the key to everything.
The Prophet (Sal Allaahu Alaiyhi wa Sallam) said: "The son of Adam does not fill any vessel worse than his stomach; for the son of Adam a few mouthfuls are sufficient to keep his back straight. If you must fill it, then one-third for food, one-third for drink and one-third for air." (Tirmidhi, Ibn Maajah. saheeh by al-Albaani).
Too much food distracts a person from many deeds of obedience and worship, makes him lazy and also makes the heart heedless.
