How to install OS in Raspberry Pi

How to Install OS in Raspberry Pi


Step 1: Download the Required Software and Files



Download Link:-

https://www.raspberrypi.org/downloads/noobs/ 


Step 2: Get the SD Card and the Card Reader





Step 3: Check the Drive in Which the SD Card Is Mounted

Go to my computer or My PC and find the drive name where the SD card is mounted.


Step 4: Format the SD Card

Open SD Card Formatter and select the drive you noticed in the previous step.

Click on format and don't alter any other options.

When formatting is completed, click on OK.


Step 5: Write the OS on the SD Card

Open win32diskimager.

Browse the .img file of Raspbian OS that was extracted from the downloaded file.

Click on open and then click on Write. If any warning pops up then ignore those by clicking OK.

Wait for the write to be completed and it may take some minutes. So be patient.


Step 6: Eject the SD Card

Now your OS in installed on your Raspberry Pi.

How to find out WiFi Password in Windows 10

Hi

Lets c how to find out the wifi password in windows 10 

First press window key + x and click on command prompt admin or windows powershell admin

or else go on thro command admin 

Write the below text to find out the password

*netsh wlan show profile "wifi name" key = clear*

Note my name is D3D den 

Lets start 

The one which i highlighted is the wifi password 


Thanks

Qari Qasim Ansari Sahib R.A Biography


ABOUT QARI MOHAMMED QASIM ANSARI SAHIB

Moulana Hafiz & Qari Mohammad Qasim Ansari Sahib's passing away on 13th September 2014 is a great loss to the community and country. As a Qari of International repute he had brought many laurels to our motherland by winning International Qirath competitions. 

Moulana Qasim Ansari Sahib was born in Bhopal in the year 1957. As a student he showed keen interest in Quran and learnt Quranic Phonetics and the art to recite Quran from "Master of Qaris" Shaikh Qari Latheefur Rahman Sahib, Yamani. He also represented India at Mecca and Malaysia in the Year 1980 and 1983 and at several other Qirath meets which had won him great Laurels. Qari Qasim Ansari Sahib was a student of Darul uloom,Islamia Arabia, Bhopal.

He was an excellent Qrator, Hafiz & Qari besides that was also former Imam and Khateeb of Perimet mosque which is one of the well known mosque in Tamilnadu. He was living in Chennai with his family - wife and three children in his flat. Eldest son is Hafiz. He served in the Periamet mosque for about 30 years. His Quranic tafseers given in Periamet mosque have been published by interested people.His qirat was recorded and uploaded in YouTube.

After coming out from the responsibility of the Periamet mosque, he was giving tafseer of Quran in mosques from time to time and attending social functions. He led taraweeh prayers every Ramadan in Anjuman-e- himayat-e-Islam mosque. Both in Periamet and Anjuman mosques people gathered in large numbers to pray under him and listen to his beautiful recitation which was most attractive in his sweet voice. 

He had a wonderful memory and his hifz of the holy Quran was perfect beyond any doubt. Moreover his Jumma khuthba was also of much interest to the people. He used to sermon to the point without indulging in any controversy.  He was for unity of the different schools of thought. We miss him miserably. 

May his soul rest in peace. Let us all pray for his maghfirath. The Qirath, Bayaan and Taraveeh's uploaded in YouTube.
